To examine breast-feeding and complementary feeding practices during the first 6 months of life among Norwegian infants of Somali and Iraqi family origin.

A cross-sectional survey was performed during March 2013–February 2014. Data were collected using a semi-quantitative FFQ adapted from the second Norwegian national dietary survey among infants in 2006–2007.

Somali-born and Iraqi-born mothers living in eastern Norway were invited to participate.

One hundred and seven mothers/infants of Somali origin and eighty mothers/infants of Iraqi origin participated.

Breast-feeding was almost universally initiated after birth. Only 7 % of Norwegian-Somali and 10 % of Norwegian-Iraqi infants were exclusively breast-fed at 4 months of age. By 1 month of age, water had been introduced to 30 % of Norwegian-Somali and 26 % of Norwegian-Iraqi infants, and infant formula to 44 % and 34 %, respectively. Fifty-four per cent of Norwegian-Somali and 68 % of Norwegian-Iraqi infants had been introduced to solid or semi-solid foods at 4 months of age. Breast-feeding at 6 months of age was more common among Norwegian-Somali infants (79 %) compared with Norwegian-Iraqi infants (58 %; P=0·001). Multivariate analyses indicated no significant factors associated with exclusive breast-feeding at 3·5 months of age. Factors positively associated with breast-feeding at 6 months were country of origin (Somalia) and parity (>2).

Breast-feeding initiation was common among Iraqi-born and Somali-born mothers, but the exclusive breast-feeding period was shorter than recommended in both groups. The study suggests that there is a need for new culture-specific approaches to support exclusive breast-feeding and complementary feeding practices among foreign-born mothers living in Norway.

We aimed to investigate the association between multiple measures of socio-economic position (SEP) and diet quality, using a diet quality index representing current national dietary guidelines, in the Australian adult population.

Cross-sectional study. Linear regression analyses were used to estimate the association between indicators of SEP (educational attainment, level of income and area-level disadvantage) and diet quality (measured using the Dietary Guideline Index (DGI)) in the total sample and stratified by sex and age (≤55 years and >55 years).

A large randomly selected sample of the Australian adult population.

Australian adults (n 9296; aged ≥25 years) from the Australian Diabetes, Obesity and Lifestyle Study.

A higher level of educational attainment and income and a lower level of area-level disadvantage were significantly associated with a higher DGI score, across the gradient of SEP. The association between indicators of SEP and DGI score was consistently stronger among those aged ≤55 years compared with their older counterparts. The most disadvantaged group had a DGI score between 2 and 5 units lower (depending on the marker of SEP) compared with the group with the least disadvantage.

A higher level of SEP was consistently associated with a higher level of diet quality for all indicators of SEP examined. In order to reduce socio-economic inequalities in diet quality, healthy eating initiatives need to act across the gradient of socio-economic disadvantage with a proportionate focus on those with greater socio-economic disadvantage.

To examine the association between protective lifestyle behaviours (PLB) and depression in middle-aged Irish adults.

Secondary analysis of a cross-sectional study. PLB (non-smoker, moderate alcohol, physical activity, adequate fruit and vegetable intake) were assessed using a general health and lifestyle questionnaire and a validated FFQ. Depression was assessed using the Center for Epidemiologic Studies Depression Scale. A score of 15–21 indicates mild/moderate depression and a score of 22 or more indicates a possibility of major depression. Binary logistic regression was used to examine the association between PLB and depression.

Livinghealth Clinic, Mitchelstown, North Cork, Republic of Ireland.

Men and women aged 50–69 years were selected at random from a list of patients registered at the clinic (n 2047, 67 % response rate).

Over 8 % of participants engaged in zero or one PLB, 24 % and 39 % had two and three PLB respectively, while 28 % had four PLB. Those who practised three/four PLB were significantly more likely to be female, have a higher level of education and were categorised as having no depressive symptoms. Engaging in zero or one PLB was significantly associated with an increased odds of depression compared with four PLB. Results remained significant after adjusting for several confounders, including age, gender, education and BMI (OR=2·2; 95 % CI 1·2, 4·0; P for trend=0·001).

While causal inference cannot be established in a cross-sectional study, the findings suggest that healthy behaviours may play a vital role in the promotion of positive mental health or, at a minimum, are associated with lower levels of depression.

Relationships among race/ethnicity, individual socio-economic status (SES), neighbourhood SES and acculturation are complex. We sought to answer whether: (i) race/ethnicity, individual SES and neighbourhood SES have independent effects on women’s fruit and vegetable consumption (FVC); (ii) SES modifies the effects of race/ethnicity on FVC; and (iii) nativity modifies the effect of Latina ethnicity on FVC.

Cross-sectional surveys from the population-based Geographic Research on Wellbeing (GROW) Study were linked with census-tract level data. FVC was indicated by (i) consuming fruits and vegetables less often than daily (LOWFV) and (ii) not having fruits and vegetables in the home very often. Other variables included age, marital status, race/ethnicity, country of birth, educational attainment, family income and longitudinal neighbourhood poverty (based on latent class growth models). Weighted logistic regression models accounting for the complex sample design were constructed.

California, USA, 2012–2013.

Women (n 2669).

In adjusted models, race/ethnicity, education and income were independently associated with FVC, but not neighbourhood poverty. Women of colour, high-school graduates and women with incomes at 301–400 % of the federal poverty level were at higher odds of LOWFV compared with non-Hispanic Whites, college graduates and those with incomes >400 % of the federal poverty level. Little evidence for interactions between race/ethnicity and individual or neighbourhood SES was found; similar patterns were observed for immigrant and US-born Latinas.

Addressing the dietary needs of lower-SES communities requires multilevel interventions that simultaneously provide culturally tailored nutrition education and address the physical and economic accessibility of culturally acceptable fruits and vegetables.

To examine pre-conception dietary patterns in pregnant asthmatic women and to identify associations between maternal diet and asthma control during pregnancy.

Cross-sectional study. Pre-conception food frequency data were collected retrospectively. Asthma control was assessed using the Global Initiative for Asthma guidelines. Dietary patterns were derived using factor analysis. Binary logistic regression analyses were used to test the association between uncontrolled asthma and each dietary pattern (Z-score), with values presented as odds ratio and 95 % confidence interval.

Antenatal clinic in a tertiary hospital, Adelaide, Australia, May 2009–July 2013.

One hundred and fifty-eight asthmatic pregnant women.

Three dietary patterns were identified: (i) ‘high protein/fruit’ (strong food group loadings for fish, meat, chicken, fruit); (ii) ‘high fat/sugar/takeaway’ (takeaway foods, crisps, refined grains); and (iii) ‘vegetarian-type’ (vegetables, fruit, soya milk, whole grains). A 1 sd increase in score on the high fat/sugar/takeaway pattern was associated with increased likelihood of uncontrolled asthma (adjusted OR=1·54; 95 % CI 1·07, 2·23; P=0·022). Women with uncontrolled asthma (n 115) had higher energy-adjusted intakes of saturated fat, monounsaturated fat, carbohydrate, sugar and fibre compared with women with controlled asthma (n 43, all P≤0·05).

Pre-pregnancy dietary patterns may influence maternal asthma control. Our work highlights the importance of achieving a healthy diet before pregnancy that is low in saturated fat, sugar and takeaway foods, and therefore higher in lean meats, poultry and fish, as well as fruits, vegetables and whole grains. A healthy dietary pattern should be encouraged in all asthmatic women who are of childbearing age, and should additionally be promoted before pregnancy and beyond.

Soda consumption is high in the USA, especially among minorities and individuals of lower socio-economic status (SES); this may be due to its affordable price in relation to healthier alternatives. The objective of the present study was to examine geospatial variation in price of milk and soda, and the price of milk relative to soda, by neighbourhood SES and proportion of Hispanic and black individuals.

Retailer soda and milk prices (n 2987; Information Resources, Inc. Academic Data Set 2004–2011) were linked to census block group sociodemographic characteristics (American Community Survey 2005–2009). Linear hierarchical regression models were used to adjust for confounders.

Large chain supermarkets and superstores (n 1743) in forty-one states and 1694 block groups (USA).

For equivalent fluid ounces, price of soda on average was 62 % lower than milk ($US 0·23 v. $US 0·63 per serving) and there was high dispersion in milk price across geographic areas. After adjustment for confounding, neighbourhoods with a higher concentration of black and Hispanic individuals tended to have lower soda prices and higher milk prices (−$US 0·001 and +$US 0·007 in price per serving, respectively, for a one quintile increase in black/Hispanic population), while soda and milk both became less expensive as SES decreased (–$US 0·002 and −$US 0·015 in serving price per one sd decrease in SES index, respectively).

Neighbourhoods with a higher concentration of blacks and Hispanics may be at greater risk of higher soda consumption due to more affordable prices, in absolute terms and relative to the price of milk.

To investigate the use of community-supported agriculture (CSA) as an employer-based health promotion intervention.

Quasi-experimental study using a convenience sample of employees at three employers.

Participants and controls from three Minnesota employers completed baseline and follow-up health assessments and surveys about their experiences with CSA.

A total of 324 participants purchased a CSA share and were eligible for study inclusion. Study participants were matched by age, sex, employer and occupation to a non-randomized control group of individuals who did not purchase a CSA share but completed health assessments during the same time frame as the study participants.

The majority of participants were female, white, middle-aged and highly educated. The most common reason for purchasing a CSA share was a desire for fresh food, and the majority of participants were satisfied with their experience. Participants reported a significant increase in the number of vegetables present in the household and the frequency of family meals. The frequency of eating out decreased significantly, especially at fast-food restaurants. Participants also reported an increase in the amount and variety of produce consumed. However, health assessment data did not show significant changes in dietary intake, health status or BMI.

CSA participation was associated with improvement in some aspects of the household environment and dietary behaviours. Further research is needed to determine whether employer-based CSA interventions may also lead to improvements in dietary intake and health.

To assess the acceptability and adherence to daily doses of lipid-based nutrient supplement (LNS) among children and micronutrient powder (MNP) among children and pregnant and lactating women.

Household interviews and sachet counting were conducted to measure acceptability and adherence, 15 and 30 d after product distribution. Qualitative information on product acceptability was collected using focus group discussions.

Saharawi refugee camps, Algeria, August–October 2009.

LNS was distributed to 123 children aged 6–35 months (LNS-C), and MNP to 112 children aged 36–59 months (MNP-C) and 119 pregnant or lactating women (MNP-W).

At the end of the test 98·4 % of LNS-C, 90·4 % of MNP-C and 75·5 % of MNP-W participants reported that they liked the product (P<0·05). Other measures of acceptability did not differ. Median consumption of sachets was highest in the LNS-C group (P<0·001). ‘Good’ adherence to the daily regimen (consumption of 75–125 % of recommended dose) was 89·1 % in the LNS-C, compared with 57·0 % in the MNP-C and 65·8 % in the MNP-W groups (P<0·001). Qualitative findings supported the quantitative measures and guided selection of local product names, packaging designs, distribution mechanisms, and the design of the information campaign in the subsequent programme scale-up.

Acceptability, consumption and adherence were higher in participants receiving LNS compared with MNP. However, both products were found to be suitable when compared with predefined acceptability criteria. Acceptability studies are feasible and important in emergency nutrition programmes when the use of novel special nutritional products is considered.

To determine the contribution of forest foods to dietary intake and estimate their association with household food insecurity.

Cross-sectional survey conducted among 279 households. Using a 7 d recall questionnaire, information on household food consumption was collected from women and used to determine the household dietary diversity score, food variety score and forest food consumption score (FFCS). Household Food Insecurity Access Scale (HFIAS) score was determined and Spearman rank correlation was used to establish the relationship between consumption of forest foods and HFIAS score. Women’s dietary intake was estimated from two 24 h recalls. The contribution of forest foods to women’s nutrient intakes was calculated and women’s nutrient intakes were compared with estimated average nutrient requirements.

Rural forest-dependent households in twelve villages in eastern and southern Cameroon.

Household heads and their non-pregnant, non-lactating spouses.

Forty-seven unique forest foods were identified; of these, seventeen were consumed by 98 % of respondents over the course of one week and by 17 % of women during the two 24 h recall periods. Although forest foods contributed approximately half of women’s total daily energy intake, considerably greater contributions were made to vitamin A (93 %), Na (100 %), Fe (85 %), Zn (88 %) and Ca (89 %) intakes. Despite a highly biodiverse pool of foods, most households (83 %) suffered from high food insecurity based on the HFIAS. A significant inverse correlation was observed between the HFIAS score and the FFCS (r2=−0·169, P=0·0006), demonstrating that forest foods play an important role in ensuring food security in these forest-dependent communities.

Forest foods are widely consumed by forest-dependent communities. Given their rich nutrient content, they have potential to contribute to food and nutrition security.

To examine the association between cardiorespiratory fitness and dietary patterns in adolescents.

Food choice was assessed using the validated New Zealand Adolescent FFQ. Principal components analysis was used to determine dietary patterns. Trained research assistants measured participants’ height and body mass. Cardiorespiratory fitness was assessed in a subset of participants using the multistage 20 m shuttle run. The level and stage were recorded, and the corresponding VO2max was calculated. Differences in mean VO2max according to sex and BMI were assessed using t tests, while associations between cardiorespiratory fitness and dietary patterns were examined using linear regression analyses adjusted for age, sex, school attended, socio-economic deprivation and BMI.

Secondary schools in Otago, New Zealand.

Students (n 279) aged 14–18 years who completed an online lifestyle survey during a class period.

Principal components analysis produced three dietary patterns: ‘Treat Foods’, ‘Fruits and Vegetables’ and ‘Basic Foods’. The 279 participants who provided questionnaire data and completed cardiorespiratory fitness testing had a mean age of 15·7 (sd 0·9) years. Mean VO2max was 45·8 (sd 6·9) ml/kg per min. The ‘Fruits and Vegetables’ pattern was positively associated with VO2max in the total sample (β=0·04; 95 %CI 0·02, 0·07), girls (β=0·06; 95 % CI 0·03, 0·10) and boys (β=0·03; 95 % CI 0·01, 0·05).

These results indicate that increase in cardiorespiratory fitness was associated with a healthier dietary pattern, suggesting both should be targeted as part of a global lifestyle approach. Longitudinal studies are needed to confirm this association in relation to health outcomes in New Zealand adolescents.

To examine the relationship between dietary cruciferous vegetable intake and selected tumour biomarkers for histone acetylation (H3K9ac, H3K18ac, HDAC3 and HDAC6), proliferation (Ki-67) and cell-cycle regulation (p21) from breast tissue.

The study used baseline data of women recruited to participate in a clinical trial of sulforaphane supplement. Dietary cruciferous vegetable intake was collected through a validated Arizona Cruciferous Vegetable Intake Questionnaire. Breast tissue was obtained from biopsy samples. Spearman correlations were calculated between intake of specific cruciferous vegetables and biomarkers. Tissue biomarkers were log2-transformed to obtain approximate normality. Linear regression analyses were conducted to examine associations between cruciferous vegetable intake and biomarkers adjusting for age and use of non-steroidal anti-inflammatory drugs. False discovery rate (FDR) was used to account for multiple comparisons.

Clinical trial baseline.

Fifty-four women who had abnormal mammogram findings and were scheduled for breast biopsy.

Mean intake of total cruciferous vegetables from all food sources was 81·7 (sd 57·3) g/d. Mean urinary total sulforaphane metabolites was 0·08 (sd 0·07) µm/mm creatinine. Total cruciferous vegetable intake was inversely associated with Ki-67 protein expression in breast ductal carcinoma in situ (DCIS) tissue (β=−0·004; se=0·001; FDR q value=0·03), but not in benign or invasive ductal carcinoma (IDC) tissue. No association was found for other biomarkers measured (HDAC3, HDAC6, H3K9, H3K18 and p21) in all tissues examined (benign, DCIS and IDC).

The present study sought to provide additional evidence for the potential role of sulforaphane in histone acetylation and cell proliferation. Here, we report that total cruciferous vegetable intake is associated with decreased cell proliferation in breast DCIS tissue.

The aims of the current report are to present the demographic characteristics, clinical characteristics/biochemical indices and lifestyle habits of the population and to explore the potential association of exclusive olive oil consumption, in relation to lifestyle factors, with coronary artery disease risk.

Demographic, lifestyle, dietary and biochemical variables were recorded. Logistic regression analysis was performed in order to estimate the relative risks of developing coronary artery disease.

The Hellenic study of Interactions between Single nucleotide polymorphisms and Eating in Atherosclerosis Susceptibility (THISEAS), a medical centre-based case–control study conducted in Greek adults.

We consecutively enrolled 1221 adult patients with coronary artery disease and 1344 adult controls.

A higher prevalence of the conventional established risk factors was observed in cases than in controls. Physical activity level was higher in controls (1·4 (sd 0·2) than in cases (1·3 (sd 0·3); P<0·001). Regarding current and ex-smokers, the case group reported almost double the pack-years of the control group (54·6 (sd 42·8) v. 28·3 (sd 26·3), respectively; P<0·001). Exclusive olive oil consumption was associated with 37 % lower likelihood of developing coronary artery disease, even after taking into account adherence to the Mediterranean diet (OR=0·63; 95 % CI 0·42, 0·93; P=0·02).

Exclusive olive oil consumption was associated with lower risk of coronary artery disease, even after adjusting for adoption of an overall healthy dietary pattern such as the Mediterranean diet.

To determine perceptions, beliefs and experiences affecting breast-feeding in Marshallese mothers residing in Northwest Arkansas, USA.

A qualitative, exploratory study using a brief survey and focus groups. Marshallese women, 18 years or older who had a child under 7 years of age, were included in the study.

Community-based organization in Northwest Arkansas.

The majority of mothers viewed breast milk as superior to formula, but had concerns about adequate milk supply and the nutritional value of their milk. The primary barriers to exclusive breast-feeding in the USA included public shaming (both verbal and non-verbal), perceived milk production and quality, and maternal employment. These barriers are not reported in the Marshall Islands and are encountered only after moving to the USA. Breast-feeding mothers rely heavily on familial support, especially the eldest female, who may not reside in the USA. The influence of institutions, including the Special Supplemental Nutrition Program for Women, Infants, and Children, is strong and may negatively affect breast-feeding.

Despite the belief that breast milk is the healthiest option, breast-feeding among Marshallese mothers is challenged by numerous barriers they encounter as they assimilate to US cultural norms. The barriers and challenges, along with the strong desire to assimilate to US culture, impact Marshallese mothers’ perceptions, beliefs and experiences with breast-feeding.

Conditional cash transfer (CCT) programmes provide income to low-income families in return for fulfilling specific behavioural conditions. CCT have been shown to improve child health, but there are few systematic studies of their impact on multiple determinants of child health. We examined the impact of a CCT programme in Colombia on: (i) use of preventive health services; (ii) food consumption and dietary diversity; (iii) mother’s knowledge, attitudes and practices about caregiving practices; (iv) maternal employment; and (v) women’s empowerment.

Secondary analysis of the quasi-experimental evaluation of the Familias en Accion programme. Children and families were assessed in 2002, 2003 and 2005–06. We applied a difference-in-differences approach using logistic or linear regression, separately examining effects for urban and rural areas.

Colombia.

Children (n 1450) and their families in thirty-one treatment municipalities were compared with children (n 1851) from sixty-five matched control municipalities.

Familias en Accion was associated with a significant increase in the probability of using preventive care services (OR=1·85, 95 % CI 1·03, 3·30) and growth and development check-ups (β=1·36, 95 % CI 0·76, 1·95). It had also a positive impact on dietary diversity and food consumption. No effect was observed on maternal employment, women’s empowerment, and knowledge, attitudes and practices about caregiving practices. Overall, Familias en Accion’s impact was more marked in rural areas.

CCT in Colombia increase contact with preventive care services and improve dietary diversity, but they are less effective in influencing mother’s employment decisions, empowerment and knowledge of caregiving practices.

To analyse the prevalence of cardiovascular risk factors in healthy adolescents of low to middle socio-economic status and to study the influence of anthropometric, biological and lifestyle factors on the risk of metabolic syndrome (MetS).

Cross-sectional study. BMI, waist circumference, blood pressure, fat and lean mass (by dual-energy X-ray absorptiometry), TAG, HDL-cholesterol, glucose, insulin, homeostatic model assessment–insulin resistance index (HOMA-IR), food intake and physical activity were measured. Cardiovascular risk factors were defined using the International Diabetes Federation criteria and insulin resistance using HOMA-IR ≥2·6. Bivariate and multivariate regressions examined the associations between MetS and anthropometric, biological and lifestyle factors.

Observational cohort study including Chilean adolescents, who were part of a follow-up study beginning in infancy.

Adolescents aged 16–17 years (n 667).

In the sample, 16·2 % had obesity and 9·5 % had MetS. Low HDL-cholesterol (69·9 %), abdominal obesity (33·3 %) and fasting hyperglycaemia (8·7 %) were the most prevalent cardiovascular risk factors. In males, obesity (OR=3·7; 95 % CI 1·2, 10·8), insulin resistance (OR=3·0; 95 % CI 1·1, 8·2), physical inactivity (OR=2·9; 95 % CI 1·1, 7·7) and sarcopenia (OR=21·2; 95 % CI 4·2, 107·5) significantly increased the risk of MetS. In females, insulin resistance (OR=4·9; 95 % CI 1·9, 12·6) and sarcopenia (OR=3·6; 95 % CI 1·1, 11·9) were significantly associated with MetS.

High prevalences of obesity, abdominal obesity, dyslipidaemia, fasting hyperglycaemia and MetS were found in healthy adolescents. In both sexes, sarcopenia and insulin resistance were important risk factors of MetS. Promotion of active lifestyles at the school level and regulation of the sale of energy-dense foods are needed.

To evaluate the nutritional situation of the victims of the 2010 landslide disaster in Uganda, food varieties consumed and coping strategies were assessed.

Cross-sectional. Food variety scores (FVS) were obtained as the total of food items eaten over the last week while an index was based on severity weighting of household food insecurity coping strategies. We included 545 affected and 533 control households.

Victims in the affected Bududa district in Eastern Uganda and those victims resettled in the Kiryandongo district, Western Uganda.

Adjusted for covariates, in Bududa significantly higher mean FVS were observed among: affected than controls; farmers than others; and relief food recipients. Control households scored higher means (se) on severity of coping: 28·6 (1·3) v. 19·2 (1·2; P<0·01). In Kiryandongo, significantly higher FVS were observed among: control households; household heads educated above primary school; those with assets that complement food source; and recipients of relief food. Severity of coping was significantly higher among affected households and non-recipients of relief food. Affected households had a higher likelihood to skip a day without eating a household meal in Bududa (OR=2·31; 95 % CI 1·62, 3·29; P<0·01) and Kiryandongo (OR=1·77; 95 % CI 1·23, 2·57; P<0·01).

Whereas FVS and severity of coping showed opposite trends in the two districts, resettlement into Kiryandongo led to severe coping experiences. Administrative measures that provide a combination of relief food, social protection and resettlement integration may offset undesirable coping strategies affecting diet.

To examine whether women’s knowledge of pregnancy-related risks and family support received during pregnancy are associated with adherence to maternal iron–folic acid (IFA) supplementation.

Secondary data analysis of the 2002–03, 2007 and 2012 Indonesia Demographic and Health Survey. Analysis of the association between factors associated with adherence (consuming ≥90 IFA tablets), including the women’s knowledge and family support, was performed using multivariate logistic regression.

National household survey.

Women (n 19 133) who had given birth within 2 years prior to the interview date.

Knowledge of pregnancy-related risks was associated with increased adherence to IFA supplementation (adjusted OR=1·8; 95 % CI 1·6, 2·0), as was full family (particularly husband’s) support (adjusted OR=1·9; 95 % CI 1·6, 2·3). Adequate antenatal care (ANC) visits (i.e. four or more) was associated with increased adherence (adjusted OR=2·2; 95 % CI 2·0, 2·4). However, ANC providers missed opportunities to distribute tablets and information, as among women with adequate ANC visits, 15 % reported never having received/bought any IFA tablets and 30 % had no knowledge of pregnancy-related risks. A significant interaction was observed between family support and the women’s educational level in predicting adherence. Family support significantly increased the adherence among women with <9 years of education.

Improving women’s knowledge of pregnancy-related risks and involving family members, particularly the husband and importantly for less-educated women, improved adherence to IFA supplementation. ANC visit opportunities must be optimized to provide women with sufficient numbers of IFA tablets along with health information (especially on pregnancy-related risks) and partner support counselling.

Using data from the national micronutrients survey 2011–2012, the present study explored the determinants of Fe status and Hb levels in Bangladesh with a particular focus on groundwater Fe.

Cross-sectional study conducted at the nationwide scale.

The survey was conducted in 150 clusters, fifty in each of the three strata of rural, urban and slum.

Three population groups: pre-school age children (6–59 months; PSAC), school age children (6–14 years; SAC) and non-pregnant non-lactating women (15–49 years; NPNLW).

National prevalence of Fe deficiency was 10·7 %, 7·1 % and 3·9–9·5 % in PSAC, NPNLW and SAC, respectively. Prevalence of anaemia was 33·1 % (PSAC), 26·0 % (NPNLW) and 17·1–19·1 % (SAC). Multivariate regression analyses showed that the area with ‘predominantly high groundwater Fe’ was a determinant of higher serum ferritin levels in NPNLW (standardized β=0·19; P=0·03), SAC (standardized β=0·22; P=0·01) and PSAC (standardized β=0·20; P=0·03). This area also determined higher levels of Hb in PSAC (standardized β=0·14; P=0·01).

National prevalence of Fe deficiency in Bangladesh is low, contrary to the widely held assumption. High Fe level in groundwater is associated with higher Fe status (all populations) and higher Hb level (PSAC).

To explore factors affecting children’s and adolescents’ diet quality, in the framework of a food aid and promotion of healthy nutrition programme implemented in areas of low socio-economic status of Greece, during the current financial crisis.

From a total of 162 schools participating in the programme during 2012–2013, we gathered 15 897 questionnaires recording sociodemographic characteristics, lifestyle parameters and dietary habits of children and their families. As a measure of socio-economic status, the Family Affluence Scale (FAS) was used; whereas for the assessment of diet quality, the KIDMED score was computed. Associations between KIDMED and FAS, physical activity and socio-economic parameters were examined using regression and classification–regression tree analysis (CART).

The higher the FAS score, the greater the percentage of children and adolescents who reported to consume, on a daily basis, fruits and vegetables, dairy products and breakfast (P<0·001). Results from CART showed that children and adolescents in the medium or high FAS groups had higher KIDMED score, compared with those in the low FAS group. For those in the low FAS group, KIDMED score is expected to increase by 12·4 % when they spend more than 0·25 h/week in sports activities. The respective threshold for the medium and high FAS groups is 1·75 h/week, while education of the mother and father affected KIDMED score significantly as well.

Diet quality is strongly influenced by socio-economic parameters in children and adolescents living in economically disadvantaged areas of Greece, so that lower family affluence is associated with worse diet quality.

To investigate the association between food insecurity and intimate partner violence in a population-based sample of heterosexual women.

Logistic regression was used to evaluate the association between three levels of food insecurity and intimate partner violence.

Data from 6 years of the California Women’s Health Survey.

Randomly selected women (n 16 562) aged 18 years and older from the State of California, USA.

We found: (i) that African-American women had a higher prevalence of food insecurity and were more likely to report severe intimate partner violence; (ii) a strong positive association between food insecurity and intimate partner violence; (iii) evidence of effect modification of the association between food insecurity and intimate partner violence by marital status; and (iv) higher odds of intimate partner violence among those reporting more severe food insecurity.

Food insecurity is an important risk indicator for intimate partner violence among women. Understanding the factors that put women, especially minority women, at greatest risk facilitates intervention development.
