To examine associations between household-level characteristics and underweight in a post-conflict population.
Design
Nutritional status of residents in the Gulu Health and Demographic Surveillance Site was obtained during a community-based cross-sectional study, ~6 years after the civil war. Household-level factors included headship, polygamy, household size, child-to-adult ratio, child crowding, living with a stunted or overweight person, deprived area, distance to health centre and socio-economic status. Multilevel logistic regression models examined associations of household and community factors with underweight, calculating OR, corresponding 95 % CI and intraclass correlation coefficients. Effect modification by gender and age was examined by interaction terms and stratified analyses.
Setting
Rural post-conflict area in northern Uganda.
Subjects
In total, 2799 households and 11 312 individuals were included, representing all age groups.
Results
Living in a female-headed v. male-headed household was associated (OR; 95 % CI) with higher odds for underweight among adult men (2·18; 1·11, 4·27) and girls <5 years (1·51; 0·97, 2·34), but lower odds among adolescent women aged 13–19 years (0·46; 0·22, 0·97). Higher odds was seen for residents living in deprived areas (1·37; 0·97, 1·94), with increasing distance to health services (P-trend <0·05) and among adult men living alone v. living in an average-sized household of seven members (3·23; 1·22, 8·59). Residents living in polygamous households had lower odds for underweight (0·79; 0·65, 0·97).
Conclusions
The gender- and age-specific associations between household-level factors and underweight are likely to reflect local social capital structures. Adapting to these is crucial before implementing health and nutrition interventions.
Short screeners for assessing dietary quality are lacking in Asia. We recently developed a short thirty-seven-item diet screener (DS). The present study aimed to evaluate reproducibility and relative validity of the DS in assessing a priori dietary quality indices (DQI; i.e. the Alternative Healthy Eating Index-2010 (AHEI-2010), alternate Mediterranean Diet (aMed) and Dietary Approaches to Stop Hypertension (DASH) diet) and intakes of selected foods.
Design
DS administration and biomarker measurement took place twice within a 4-month interval. A 163-item FFQ was administered one month after the second DS administration.
Setting
Singapore, a multi-ethnic urban Asian country.
Subjects
Singapore residents (n 161) aged 18–79 years, of Chinese, Malay and Indian ethnicity.
Results
Reproducibility coefficients for the two DS were 0·71 (DQI) and 0·65 (food groups). Correlations (ρ) between mean DS and FFQ DQI scores were 0·51 (AHEI-2010), 0·50 (aMed) and 0·61 (DASH; all P<0·05). Cohen’s weighted kappa indicated moderate agreement between the two measures (κw=0·48–0·58). DS DQI scores were associated with concentrations of β-cryptoxanthin (AHEI-2010, ρ=0·26; P<0·05), odd-chain SFA (aMed, ρ=0·24; DASH, ρ=0·25; both P<0·05), and enterolactone, total carotenoids, PUFA and α-linolenic acid (all scores, ρ=0·17–0·30; all P<0·05). Scores were not associated with isoflavone or long-chain n-3 PUFA concentrations.
Conclusions
A short screener can be used to assess DQI with good reproducibility and relative validity compared with a longer FFQ in an Asian population.
To assess the relative validity of a new, web-based, self-administered 24 h dietary recall, the R24W, for assessment of energy and nutrient intakes among French Canadians.
Design
Each participant completed a 3d food record (FR) and the R24W on three occasions over a 4-week period. Intakes of energy and of twenty-four selected nutrients assessed by both methods were compared.
Setting
Québec City metropolitan area.
Subjects
Fifty-seven women and fifty men (mean (sd) age: 47·2 (13·3) years).
Results
Equivalent proportions of under-reporters were found with the R24W (15·0%) and the FR (23·4%). Mean (sd) energy intake from the R24W was 7·2% higher than that from the FR (10 857 (3184) kJ/d (2595 (761) kcal/d) v. 10 075 (2971) kJ/d (2408 (710) kcal/d); P<0·01). Significant differences in mean nutrient intakes between the R24W and the FR ranged from –54·8% (i.e. lower value with R24W) for niacin to +40·0% (i.e. higher value with R24W) for alcohol. Sex- and energy-adjusted deattenuated correlations between the two methods were significant for all nutrients except Zn (range: 0·35–0·72; P<0·01). Cross-classification demonstrated that 40·0% of participants were classified in the same quartile with both methods, while 40·0% were classified in the adjacent quartile and only 3·6% were grossly misclassified (1st v. 4th quartile). Analysis of Bland–Altman plots revealed proportional bias between the two assessment methods for 8/24 nutrients.
Conclusions
These data suggest that the R24W presents an acceptable relative validity as compared with the FR for estimating usual dietary intakes in a cohort of French Canadians.
The present study aimed to assess the: (i) internal structure of the Spanish Child Food Security Survey Module (CFSSM-S) with exploratory and confirmatory factor analysis (EFA and CFA); (ii) measurement invariance by gender, grade, weight status, socio-economic status (SES) and family affluence; and (iii) relationships with these external variables.
Design
A cross-sectional study was conducted. The CFSSM-S and other tools were employed to assess food insecurity, weight status, SES and family affluence, respectively.
Setting
A secondary school (grades 7–10) in the city of Terrassa in Catalonia, Spain.
Subjects
Participants included adolescent boys and girls (n 426) aged 12–17 years.
Results
The cross-validation design with EFA and CFA captured a single factor, ‘food insecurity’. The goodness-of-fit for the one-factor model with CFA (root-mean-square error of approximation=0·038, comparative fit index=0·984, Tucker–Lewis index=0·979) and internal consistency (ω=0·95) were excellent. The measurement invariance indicated that CFSSM-S could be used across genders, grades, weight status, SES and family affluence. Only mean differences for SES and family affluence were found which showed a linear trend, indicating higher CFSSM-S scores for participants with lower SES and family affluence. Of participants, 1·9 % experienced very low food security, 16·4 % low food security and 81·7 % were food secure.
Conclusions
The CFSSM-S is the first validated instrument to assess food insecurity with psychometric guarantees in Spanish adolescents. Researchers and health practitioners in Spain could use this self-reported questionnaire to gain more information about adolescent health in relation to food insecurity.
The current study investigated the impact of different front-of-pack messages on liking, salt perception and table salt use of salt-reduced soups over repeated consumption.
Design
In a between-subjects design, participants consumed a chicken noodle soup five times over 3 weeks. Participants were assigned to one of five experimental conditions and were categorized into three ‘Interest in Salt Reduction’ groups based on their self-reported interest in salt reduction. They consumed a regular-salt soup or a 30 % salt-reduced soup, either with or without a front-of-pack message (nutritional, sensory or social based). Liking, salt perception and table salt use were measured at each consumption.
Setting
Central location test.
Subjects
British consumers (n 493) aged 24–65 years.
Results
The soups remained stable in liking over repeated consumption, with no significant differences between the experimental conditions. However, liking did differ among the different Interest in Salt Reduction groups: the ‘not aware, no action’ group liked salt-reduced soups with a nutritional message the most, whereas the ‘aware and action’ group liked salt-reduced soups with a social message the most. There was no change in the amount of table salt added as people got more familiar with the salt-reduced soups, suggesting a strong role for habit in table salt use.
Conclusions
It mattered whether consumers were thinking about reducing their salt intake or not: a communication message tailored to a country’s interest in reducing salt is recommended to motivate consumers to lower their salt intake.
By clearly conveying the healthiness of a food, front-of-pack (FOP) labels have the potential to influence the portion size considered appropriate for consumption. The present study examined the how the Daily Intake Guide (DIG), Multiple Traffic Lights (MTL) and Health Star Rating (HSR) FOP labels affect judgements of appropriate portion sizes of unhealthy foods compared with when no FOP label is present.
Design
Respondents viewed mock packages of unhealthy variations of pizzas, cookies, yoghurts and cornflakes featuring the DIG, MTL, HSR or no FOP label, and indicated the portion size they believed should be eaten of each food on a single occasion.
Setting
The survey was completed on the respondent’s personal computer.
Subjects
A total of 1505 Australian adults provided 4166 ratings across 192 mock packages relating to four product categories: pizza, yoghurt, cornflakes and cookies.
Results
Compared with no FOP label, the HSR resulted in a small but significant reduction in the portion size selected as appropriate for consumption of pizzas and cornflakes (P<0·05). The MTL resulted in smaller portions of cornflakes being selected compared with no FOP label (P<0·05).
Conclusions
Respondents perceived smaller portion sizes as appropriate for some, but not all, of the foods tested when FOP labels with more interpretative formats (HSR, MTL) appeared on-pack compared with no FOP label. No effect was found for the less interpretive FOP label (the DIG). Interpretive FOP labels may have the potential to influence portion size judgements, albeit at modest levels.
To examine the associations of individual and food environmental factors with fruit and vegetable (F&V) intake in a city in a low-to-middle-income country (LMIC).
Design
Cross-sectional.
Setting
Representative sample of the Brazilian Primary Care service known as the Health Academy Program (HAP) in Belo Horizonte, a Brazilian city.
Subjects
Using a conceptual model as a guide, individual and food environment data were obtained through: (i) face-to-face interviews with participants aged 20 years or older; and (ii) F&V food store audits. A broad set of individual, household, and community and consumer nutrition environment variables was investigated. Multilevel linear regression was used to quantify area-level variations in F&V intake and to estimate associations with the factors.
Results
Eighteen HAP centres were selected and 2944 participants and 336 food stores were included. F&V intake varied between contexts, being higher in areas with better socio-economic conditions and food store quality, such as specialised F&V markets. Individual-level factors, including age, income, food insecurity, stage of change, self-efficacy and decisional balance, were significantly associated with F&V intake. After controlling for individual-level characteristics, greater F&V intake was also associated with higher quality of food stores.
Conclusions
In one of the first studies to comprehensively assess the food environment in an LMIC, individual-level factors accounted for the largest variation in F&V intake; however, the food environment was also important, because area-level variables explained 10·5 % of the F&V intake variation. The consumer nutrition environment was more predictive of healthy eating than was the community nutrition environment. The findings suggest new possibilities for interventions.
The present study aimed to determine the prevalence of anaemia, iron deficiency (ID) and iron-deficiency anaemia (IDA) among female adolescents in the Gaza Strip, Palestine, as well as the risk factors involved in these conditions.
Design
The study was conducted using the quantitative descriptive method with a cross-sectional design. Data were collected using an FFQ and sociodemographic, sedentary behaviour and physical activity questionnaires. Anthropometric measurements and blood analyses were also conducted.
Setting
The study population included all Palestinian female adolescents enrolled in secondary schools in the academic years 2015–2016. Five female secondary schools were selected randomly from five governorates of the Gaza Strip.
Subjects
Female adolescents (n 330) aged 15–19 years in the selected secondary schools were enrolled randomly.
Results
Prevalence of anaemia, ID and IDA among female adolescents in the Gaza Strip, Palestine, was 35·8, 40·3 and 26·0 %, respectively. A significant association (P<0·05) existed between ID, anaemia and IDA and dietary habits, including skipping breakfast and amount of junk food intake. Also, low consumption of fruits and vegetables was associated with IDA in the female adolescents. A statistically significant association was found between mother’s education and ID but not with the other sociodemographic factors.
Conclusions
The study shows that there is an alarming problem of anaemia and IDA in the Gaza Strip, Palestine. This may indicate that there are insufficient nutrition education programmes, particularly inside schools or by the mass media.
To estimate the prevalence of overweight and obesity among children and adolescents in north Jordan and to evaluate the dietary knowledge of their mothers.
Design
Cross-sectional study.
Settings
Schools, Irbid, Jordan.
Subjects
Male and female participants (n 516) aged 6–18 years.
Results
Thirty per cent of our sample population was overweight or obese, and about 11 % was underweight. Males tend to have a higher BMI and waist circumference than females except in the age group ≥15 years. Children who ate in front of the television tended to have higher BMI and waist circumference. Forty per cent of the mothers answered four or more questions correctly out of six, which indicated a sufficient level of nutritional knowledge.
Conclusions
The study revealed that obesity is a growing health problem in children and adolescents in north Jordan. This finding is considered a serious concern for public health and calls for the creation of new prevention programmes at the individual, family and community level.
To evaluate the process of implementation of a national nutritional programme for improving the nutritional status of children in Iran.
Design
A cross-sectional process evaluation was carried out using field observations, document reviews, semi-structured interviews and focus group discussions.
Setting
Data were collected across urban and rural areas of Qazvin and Semnan provinces of Iran, March–September 2014.
Subjects
Mothers (n 362) of children under programme coverage were chosen for the survey. Senior nutrition officers, the head of Hygiene, Remedy and Insurance Affairs at Imam Khomeini Relief Foundation and community health workers were selected purposively for interviews. Mothers with at least one child under 6 years of age covered by the programme were selected to participate in focus group discussions.
Results
Five steps of programme implementation were identified: supplementary food basket content, food basket distribution methods, selection of eligible children, distributed food consumption, and child growth monitoring and nutrition training sessions for mothers. The distributed food baskets did not have enough milk/dairy products, vegetables and fruits. Nearly 50 % of children consumed 75–100 % of the distributed milk and cake/biscuit, while staple foods were shared with other family members. When electronic cards were offered instead of food baskets, attendance for child growth monitoring and the food items participants chose with the cards tended to differ from what was originally designed.
Conclusions
Focusing on food items that are mostly being used for child feeding (e.g. eggs or milk in food baskets) may be beneficial to assure the target child is receiving the distributed foods.
To examine the types of coping strategies practised by Indigenous women or Orang Asli (OA) in Peninsular Malaysia during times of food shortage and to determine the level of severity for food insecurity that will trigger each specific coping strategy.
Design
A qualitative case study was conducted. Pertinent information about each type of coping strategy was gathered by in-depth interviews. To gauge the level of severity for each of the coping strategies, focus group discussions (FGD) were held. Thematic analysis was used for data analysis.
Setting
OA villages in the states of Kelantan, Pahang, Perak and Selangor, Malaysia.
Subjects
Sixty-one OA women from three ethnic groups (Senoi, Proto-Malay and Negrito) for in-depth interviews and nineteen OA women from the Proto-Malay ethnic group for three FGD.
Results
The findings identified twenty-nine different coping strategies and these were divided into two main themes: food consumption (sub-themes of food consumption included dietary changes, diversification of food sources, decreasing the number of people and rationing) and financial management (sub-themes of financial management included increasing household income, reducing expenses for schooling children and reducing expenses on daily necessities). Three levels of severity were derived: less severe, severe and very severe.
Conclusions
This information would enable local authorities or non-governmental organisations to more precisely target and plan interventions to better aid the OA communities needing assistance in the areas of food sources and financial management.
The present study explored recipients’ perceptions of food charity and their suggested improvements in inner-city Perth, Western Australia.
Design
In-depth interviews were conducted with charitable food service (CFS) recipients. Transcripts were thematically analysed using a phenomenological approach.
Setting
Interviews were conducted at two CFS in inner-city Perth.
Subjects
Fourteen adults.
Results
The recipients’ journeys to a reliance on CFS were varied and multifactorial, with poverty, medical issues and homelessness common. The length of time recipients had relied on food charity ranged from 8 months to over 40 years. Most were ‘grateful yet resigned’, appreciative of any food and resigned to the poor quality, monotony and their unmet individual preferences. They wanted healthier food, more variety and better quality. Accessing services was described as a ‘full-time job’ fraught with unreliable information and transport difficulties. They called for improved information and assistance with transport. ‘Eroded dignity’ resulted from being fed without any choice and queuing for food in public places, often in a volatile environment. ‘Food memories and inclusion’ reflected a desire for commensality. Recipients suggested services offer choice and promote independence, focusing on their needs both physical and social.
Conclusions
Although grateful, long-term CFS recipients described what constitutes a voluntary failure. Their service improvement recommendations can help meet their nutritional and social needs. A successful CFS provides a food service that prioritises nutritious, good-quality food and individual need, while promoting dignity and social inclusion, challenging in the current Australian context.
To examine associations between availability of fast-food restaurants and convenience stores in the home and school neighbourhoods, considered separately and together, and adolescents’ fast-food and sugar-sweetened beverage (SSB) intakes.
Design
Cross-sectional observational study.
Setting
East London, UK.
Subjects
Adolescents (n 3089; aged 13–15 years) from the Olympic Regeneration in East London (ORiEL) Study self-reported their weekly frequency of fast-food and SSB consumption. We used food business addresses collected from local authority registers to derive absolute (counts) and relative (proportions) exposure measures to fast-food restaurants and convenience stores within 800 m from home, school, and home and school combined. Associations between absolute and relative measures of the food environment and fast-food and SSB intakes were assessed using Poisson regression models with robust standard errors.
Results
Absolute exposure to fast-food restaurants or convenience stores in the home, school, or combined home and school neighbourhoods was not associated with any of the outcomes. High SSB intake was associated with relative exposure to convenience stores in the residential neighbourhood (risk ratio=1·45; 95 % CI 1·08, 1·96) and in the home and school neighbourhoods combined (risk ratio=1·69; 95 % CI 1·11, 2·57).
Conclusions
We found no evidence of an association between absolute exposure to fast-food restaurants and convenience stores around home and school and adolescents’ fast-food and SSB intakes. Relative exposure, which measures the local diversity of the neighbourhood food environment, was positively associated with SSB intake. Relative measures of the food environment may better capture the environmental risks for poor diet than absolute measures.
Zn deficiency and diarrhoea are prevalent and may coexist in children living in low-resource settings. Recently, a novel approach for delivering Zn via microbiologically treated, Zn-fortified water was shown to be effective in improving Zn status in West African schoolchildren. We assessed the effectiveness of Zn-fortified, microbiologically purified water delivered as a household intervention on Zn intake, status and morbidity in children aged 2–6 years from rural western Kenya.
Design
Randomised controlled trial. Intervention included households assigned to water treatment device with (ZFW) or without (FW) Zn delivery capability
Setting
Rural households in Kisumu, western Kenya.
Subjects
Children aged 2–6 years.
Results
The ZFW group had higher dietary Zn intake compared with the FW group. ZFW contributed 36 and 31 % of daily requirements for absorbable Zn in children aged 2–3 and 4–6 years, respectively, in the ZFW group. Consumption of Zn-fortified water resulted in lower prevalence of reported illness (risk ratio; 95 % CI) in the ZFW group compared with the FW group: for cold with runny nose (0·91; 0·83, 0·99; P=0·034) and abdominal pain (0·70; 0·56, 0·89; P=0·003) in the intention-to-treat analysis and for diarrhoea (0·72; 0·53, 0·96; P=0·025) in the per-protocol analysis. We did not detect an effect of treatment on plasma Zn concentration.
Conclusions
Daily consumption of Zn-fortified, microbiologically treated water results in increased intake of absorbable dietary Zn and may help in preventing childhood infections in pre-school children in rural Africa.
To examine perspectives on food access among low-income families participating in a cost-offset community-supported agriculture (CO-CSA) programme.
Design
Farm Fresh Foods for Healthy Kids (F3HK) is a multicentre randomized intervention trial assessing the effect of CO-CSA on dietary intake and quality among children from low-income families. Focus groups were conducted at the end of the first CO-CSA season. Participants were interviewed about programme experiences, framed by five dimensions of food access: availability, accessibility, affordability, acceptability and accommodation. Transcribed data were coded on these dimensions plus emergent themes.
Setting
Nine communities in the US states of New York, North Carolina, Washington and Vermont.
Subjects
Fifty-three F3HK adults with children.
Results
CSA models were structured by partner farms. Produce quantity was abundant; however, availability was enhanced for participants who were able to select their own produce items. Flexible CSA pick-up times and locations made produce pick-up more accessible. Despite being affordable to most, payment timing was a barrier for some. Unfamiliar foods and quick spoilage hindered acceptability through challenging meal planning, despite accommodations that included preparation advice.
Conclusions
Although CO-CSA may facilitate increased access to fruits and vegetables for low-income families, perceptions of positive diet change may be limited by the ability to incorporate share pick-up into regular travel patterns and meal planning. Food waste concerns may be particularly acute for families with constrained resources. Future research should examine whether CO-CSA with flexible logistics and produce self-selection are sustainable for low-income families and CSA farms.
To examine level of participation and satisfaction with the Healthy Savings Program (HSP), a programme that provides price discounts on healthier foods.
Design
For Study 1, a survey was distributed to a random sample of adults who were invited to participate in a version of the HSP that provided a discount for the purchase of fresh produce and discounts on other healthier foods. In Study 2, interviews were conducted with a convenience sample of adults invited to participate in a version of the HSP that provided price discounts on specific products only (no fresh produce discount).
Setting
The HSP is provided to all employer-based insurance plan members of a large health plan. Employers can choose to enhance the version of the HSP that their employees receive by paying for a weekly discount on fresh produce.
Subjects
Employees in employer groups that received the enhanced HSP (Study 1) and employees in an employer group (Study 2) that received the standard HSP.
Results
Among survey respondents in Study 1, 69·3 % reported using the HSP card. Most were satisfied with the fresh produce discount and ease of use of the HSP card. Satisfaction was lower for selection of participating stores, amounts of discounts and selection of discounted products. In Study 2, barriers to the use of the HSP card cited included the limited number of participating stores and the limited selection of discounted products.
Conclusions
Satisfaction with some elements of the HSP was high while other elements may need improvement to increase programme use.
To develop a descriptive account of parents’ experiences of written feedback from the National Child Measurement Programme (NCMP), based on primary data collected from semi-structured focus groups.
Design
Four focus groups were held with a purposive sample of parents who had recently received written weight feedback from the NCMP in one local authority in England. Thematic data analysis was undertaken to develop a narrative of emergent themes regarding parents’ experiences and the social influences shaping this.
Setting/Subjects
The population of interest was parents of 4- and 5-year-olds who had recently received written feedback from the NCMP. Eighteen parents participated and represented the full spectrum of categories provided in NCMP feedback (under-, healthy, over- and very overweight).
Results
Participants often rejected overweight feedback as lacking in credibility and considered NCMP communication to be targeting parents other than themselves. Family and peers collaborated in the dismissal of overweight feedback, further legitimising participants’ decision to disregard their child’s overweight categorisation.
Conclusions
Our study provides an insight into parents’ experiences of NCMP feedback, including how they relate to and understand that experience within a social context. By doing so, it makes a unique contribution to the existing body of evidence. Recommendations for practice based on the findings include further efforts to raise parents’ and communities’ awareness of childhood obesity, risks associated with childhood excess weight and obesity prevalence as a mainstream issue.
