To investigate the effect of maternal depressive symptom trajectories, from 3 months to 11 years postpartum, on the offspring’s body composition at 11 years of age.

Data from the Pelotas 2004 Birth Cohort, from the perinatal interview and from the 3-, 12-, 24- and 48-month and 6- and 11-year follow-ups.

Community-based sample from the city of Pelotas, located in southern Brazil with approximately 350 000 inhabitants. The maternal depression symptom trajectories were identified through a semi-parametric group-based modelling approach, using the Edinburgh Postnatal Depression Scale (EPDS), with data from 3 months to 11 years postpartum.

A total of 3467 (81·9 % of the total cohort).

Five trajectory groups of EPDS scores were identified (‘Low’, ‘Moderate low’, ‘Increasing’, ‘Decreasing’ and ‘Chronic high’). A total of 170 women (4·9 %) from the sample belonged to the ‘Chronic high’ group, having scored ≥13 EPDS points at every follow-up. Mean BMI in the ‘Low’ trajectory group was 0·77 (z-score 1·4), compared with 0·56 (z-score 1·4) in the ‘Chronic high’ group. Children from mothers in the ‘Chronic high’ group had lower fat mass (FM) (–1·34 ± 0·64 kg), FM% (–2·02 ± 0·85 percentage points) and FM index (–0·57 ± 0·27 kg/m2), compared with children from mothers in the ‘Low’ trajectory group. Adjusted analyses showed that sustained or transitory maternal depressive symptoms during childhood had no effect on the offspring’s body composition indices at 11 years of age.

Children raised by chronically depressed mothers have body composition indices at 11 years of age that are similar to those of children whose mothers have never been depressed.

A social network is a valuable resource in later life. Therefore, the current study aims to investigate whether social networks within homes and neighbourhoods are associated with older adults’ daily fruit and vegetable consumption.

Cross-sectional secondary data analysis.

USA.

A nationally representative sample of 6865 community-dwelling older adults over age 53 in the Health and Retirement Study – Health Care and Nutrition Survey.

Older adults who lived alone with no children or friends nearby had the lowest fruit and vegetable consumption. However, the daily fruit and vegetable consumption of respondents who lived alone and had children or friends nearby or those who lived with someone and had no children or friends nearby was not statistically different from those who lived with someone and had children or friends nearby. This suggests that having a social network either at home or in the neighbourhood complements the absence of living with someone or having children or friends nearby and attenuates the negative association between limited social networks and daily fruit and vegetable consumption. A greater decrease in the number of fruits and vegetables consumed was observed among men when they lived alone with no children or friends nearby.

Special attention should be given to older adults with limited social networks, especially older adults living alone with no children or friends nearby. Provision of help with grocery shopping and meal preparation as well as social support networks and more opportunities that can improve social engagement appear to be necessary.

The present study aimed to examine the temporal prevalence of overweight and obesity in Irish children through different methodologies and evaluate the change in rates between 1990 and 2019.

Anthropometric data from three Irish national food consumption surveys were used to examine the change in the prevalence of BMI and waist circumference-derived overweight and obesity levels.

Three cross-sectional food consumption surveys from the Republic of Ireland: the Irish National Nutrition Survey (1990), the National Children’s Food Survey (2005) and The Second National Children’s Food Survey (2019).

A demographically representative sample of Irish children aged 5–12 years: 1990 (n 148), 2005 (n 594) and 2019 (n 596).

Twelve percentage of children had overweight/obesity in 1990, which was significantly higher in 2005 at 25 % and significantly lower in 2019 at 16 % (P = 0·003). In 2019, more girls had overweight/obesity in comparison with boys (19 v. 14 %), whilst children from the lowest social class group had the highest levels of overweight/obesity (P = 0·019). Overall, the proportion of children with abdominal overweight/obesity was significantly lower in 2019 in comparison with 2005 (P ≤ 0·001).

Evidence from the most recent national survey suggests that overweight and obesity levels are plateauing and in some cases reducing in children in Ireland. Despite this, rates remain high, with the highest prevalence in 2019 observed in girls and in those from the lowest social class group. Thus, overweight/obesity prevention and intervention policies are necessary and should be continued.

To examine demographic and behavioural correlates of frequent consumption of fast food among Australian secondary school students and explore the associations between fast food consumption and social/environmental factors.

Cross-sectional survey using a web-based self-report questionnaire.

Secondary schools across all Australian states and territories.

Students aged 12–17 years participating in the 2012–2013 National Secondary Students’ Diet and Activity survey (n 8392).

Overall, 38 % of students surveyed reported consuming fast food at least weekly. Being male, residing in lower socio-economic areas and metropolitan locations, having more weekly spending money and working at a fast food outlet were all independently associated with consuming fast food once a week or more, as were several unhealthy eating (low vegetable intake and high sugary drink and snack food intake) and leisure (low physical activity and higher commercial television viewing) behaviours and short sleep duration. Frequent fast food consumption and measured weight status were unrelated. Students who agreed they go to fast food outlets with their family and friends were more likely to report consuming fast food at least weekly, as were those who usually ‘upsize’ their fast food meals and believe fast food is good value for money.

These results suggest that frequent fast food consumption clusters with other unhealthy behaviours. Policy and educational interventions that reach identified at-risk groups are needed to reduce adolescent fast food consumption at the population level. Policies placing restrictions on the portion sizes of fast food may also help adolescents limit their intake.

To examine mediation by (i) diet quality and (ii) diet quantity in the associations of mindful eating domains with 3-year change in depressive symptoms.

Depressive symptoms were measured with the Center for Epidemiologic Studies Depression scale at baseline and 3-year follow-up. Four mindful eating domains (Focused Eating; Eating in response to Hunger and Satiety Cues; Eating with Awareness; Eating without Distraction) were measured with the Mindful Eating Behavior Scale. Food intake was measured with a 238-item FFQ. Diet quality was defined as the Mediterranean Diet Score (MDS). Diet quantity was defined as total energy intake (kcal/d; 1 kcal = 4·184 kJ). Mediation analyses with percentile-corrected bootstrap confidence intervals were conducted to calculate indirect effects.

Longitudinal Aging Study Amsterdam.

Adults aged 55 years or above (n 929).

Diet quality (MDS) did not mediate associations of any of the four mindful eating domains with change in depressive symptoms. In contrast, total energy intake did mediate the associations with change in depressive symptoms for the mindful eating domains Eating with Awareness (indirect effects fully adjusted models: B = −0·014, 95 % CI −0·037, −0·002) and Eating without Distraction (B = −0·013, 95 % CI −0·033, −0·001), but not for the other two domains. Post hoc multiple mediation analyses showed similar results.

Higher scores on two mindful eating domains were associated with a decrease in depressive symptoms through lower total energy intake. Diet quantity, but not diet quality, could be a possible underlying mechanism in the associations between mindful eating and change in depressive symptoms.

Within- and across-country nutritional disparities were examined among older adults in six different countries at varying levels of development.

Cross-sectional study.

Older adults (aged 50 years or over) in China, Ghana, India, Mexico, Russia and South Africa using the Study on global AGEing and adult health (SAGE).

While the distribution of BMI categories varied by country, development-related characteristics were generally related to BMI category in a similar way: urban-living, educated and wealthier individuals were typically more likely to be in a higher BMI category. However, there were some exceptions that corroborate findings in more developed countries. Indeed, a pooled partial proportional odds model which included gross domestic product per capita interactions made the case for intertwining processes of development and the nutrition transition.

Population segments to be targeted by nutrition policy and programme implementation might need to change over the course of development.

The development of user-friendly nutrition resources for pregnant women seldom involves end-users. This qualitative study used a citizens’ jury approach to determine if our modification of a longstanding, frequently used dietitian-informed diet and diabetes booklet was deemed to be a good healthy eating resource for pregnant women.

Midwives recruited thirteen first-time pregnant women not requiring specialist obstetric care or specialist dietetic advice for any reason. Participants were sent a copy of the modified healthy eating in pregnancy booklet prior to ‘jury day’. Five women were unable to attend the citizens’ jury citing reasons such as early labour. At the jury, five experts presented evidence. Participants adjourned, with an independent facilitator, to ‘deliberate’ as to whether the resource was suitable or not. The verdict was presented, and subsequent discussion was audio-recorded, transcribed and inductively content analysed.

Southland, New Zealand.

Pregnant women aged 19–35 years (n 8), of whom half had a household income <$NZ30 000.

The verdict was ‘Yes’; the resource was good. Three themes were derived: communication of health information, resource content and harm reduction in pregnancy. Based on these data, ways to enhance the quality and usability of the booklet were evident.

Citizens’ juries can be used to obtain an independent assessment by end-users of health resources. Our modified diet and diabetes booklet was considered suitable for providing healthy eating advice to pregnant women. Inclusion of end-users’ perspectives is critical for end-user relevant content, comprehension and resource credibility.

Consumption of fruits and vegetables (F&V) among adolescents falls below recommendations in many Western countries. The impact of social and emotional aspects of family life on adolescent dietary behaviour may contribute to this, yet remains under-investigated. The present study examines the association between adolescents’ perceptions of emotional home atmosphere (EHA) and their F&V consumption frequency.

An FFQ was used to assess F&V consumption frequency. EHA was assessed by an eight-item measure with three subscales: perceived home warmth, strictness and relational tension. EHA subscales were used as binary variables: a score equal to or above the median value was considered as a higher perception, while a score below the median was considered as a lower perception of the EHA in question. Country differences in meeting the European 5-a-day recommendations were described. Further, the association between EHA and F&V consumption frequency was investigated using multiple linear regression.

Regional examination centres in eight European countries.

Adolescents (n 3196) aged 12–18 years.

The mean F&V consumption frequency was 3·27 (sd 2·84) times/d. Only 16·1 % of boys and 18 % of girls in our study sample met the recommendation of five F&V daily. After controlling for age, sex, education level of the parents and country of origin, perceived home warmth was associated with a 16 (95 % CI 9, 22) % higher F&V consumption frequency (P < 0·001).

F&V consumption frequency was suboptimal in the survey areas. Interventions targeting perceived warmth as a component of EHA could potentially have a positive effect on adolescents’ dietary behaviour.

The present study aimed to explore the associations between social life and adherence to a healthy dietary pattern, the Mediterranean diet (MD), in a population-representative cohort of older people.

Cross-sectional study. Adherence to the MD was evaluated by an a priori score; tertiles of the score, indicating low, medium and high adherence, were used in the analyses. Social life was assessed by a questionnaire evaluating participation in leisure-time activities and the number of social contacts; primary occupation was also recorded and job characteristics were further explored.

Community-dwelling older adults.

Adults from the Hellenic Longitudinal Investigation of Aging and Diet (HELIAD) study (n 1933; age range 65–99 years).

Each unit increase in the number of social contacts/month and in the frequency score of intellectual, social and physical activities was associated with a 1·6, 6·8, 4·8 and 13·7 % increase in the likelihood of a participant being in the high MD adherence group, respectively. The analysis by age group revealed that younger elderly participants had a 1·4, 8·4 and 11·3 % higher likelihood to be in the high adherence group for each unit increase in the number of social contacts/month and in the frequency score of engagement in intellectual and physical activities, respectively. Similar associations were found for older elderly participants with high compared with low MD adherence, except for the intellectual activities.

The present results suggest that high MD adherence is associated with good social life, suggesting a clustering of health-promoting lifestyle factors in older adults.

To assess the associations among eating behaviour traits, food label use and diet quality and to evaluate if the association between eating behaviour traits and diet quality is mediated by food label use.

Eating behaviour traits were assessed using the Three-Factor Eating Questionnaire (TFEQ), the Restraint Scale and the Intuitive Eating Scale, whereas food label use was measured with the Label Reading Survey. Diet quality (Canadian Healthy Eating Index) was assessed with an FFQ.

Cross-sectional study.

Adults (n 385; mean (sd): BMI = 26·0 (4·9) kg/m2, age = 41·1 (15·0) years) involved in two previous experimental studies.

When controlling for potential covariates, general food label use (β = 1·18 (se 0·26), P < 0·0001) was the main determinant of diet quality, explaining 6·7 % of its variance. General food label use partly mediated the association between TFEQ-cognitive restraint and diet quality; the indirect effect (βindirect (se); 95 % CI) was stronger in men (0·32 (0·10); 0·15, 0·55) than women (0·16 (0·05); 0·08, 0·27). General food label use also partly mediated the negative association between unconditional permission to eat and diet quality; the indirect effect (βindirect (se); 95 % CI) was also stronger in men (−1·88 (0·55); −3·11, −0·96) than women (−1·03 (0·33); −1·81, −0·49).

General food label use was the main determinant of diet quality and partly mediated the association between eating behaviour traits and diet quality. The stronger mediating effect observed in men suggests they rely more on food labelling when attempting to restrained themselves, which translates into better diet quality.

Although several studies in Western countries show that higher socioeconomic status is associated with higher diet quality, no study has observed this association in Japan. In the current study, we examined the association between diet quality and the combinations of age, sex, and household income, and also compared the dietary intake between diet quality levels according to household income.

Cross-sectional study.

National Health and Nutrition Survey, Japan in 2014.

2785 men and 3215 women.

Higher Japanese Food Guide Spinning Top scores (better diet quality) were observed in older women, especially those with higher household income, whereas lower scores were observed in younger men with lower household income. Those having low quality diet, especially in low income households, had higher odds of not meeting the recommended amounts of the Japanese dietary guidelines, than those having high quality diet.

Diet quality in Japanese adults differed by age and sex as well as by household income level. A different approach to diet quality improvement is needed according to population characteristics including not only age and sex but also social economic status.

The aim of this study was an assessment of the effects of urbanisation level, family size and parental education on body mass index (BMI) and mid-upper arm circumference (MUAC) among Polish schoolchildren in cross-sectional surveys conducted between 1966 and 2012.

The analysis involved schoolchildren measured in four Polish Anthropological Surveys (1966, 1978, 1988 and 2012). Socio-economic factors involved: urbanisation level (city, town and village), family size (one child, two children, three children, four or more children), and father’s and mother’s education (lower and higher education).

Regions in Poland – cities: Warsaw, Lodz and Wroclaw; towns: Bystrzyca Klodzka, Pinczow, Siemiatycze, Wolsztyn and their rural surroundings.

A total sample consisted of 63 757 children (31 774 boys and 31 983 girls) aged 7–18 years.

Between 1966 and 1988, both BMI and MUAC had significantly higher values in children from cities, in families with one child and with higher parental education (P < 0·05). However, MUAC revealed significant differences between particular socio-economic groups more frequently than BMI. In 2012, urbanisation level and parental education ceased to show a differentiating effect on both indicators, while family size remained a significant social factor for both measures (BMI: P < 0·05; MUAC: P < 0·01).

Since MUAC reflected socio-economic differences more frequently than BMI, it could be a more sensitive and reliable anthropometric measure revealing the effects of socio-economic factors on children’s nutritional status.

Using a legal standard for scrutinising the regulation of food label claims, this study assessed whether consumers are misled about wholegrain (WG) content and product healthfulness based on common product labels.

First, a discrete choice experiment used pairs of hypothetical products with different amounts of WG, sugar and salt to measure effects on assessment of healthfulness; and second, a WG content comprehension assessment used actual product labels to assess respondent understanding.

Online national panel survey.

For a representative sample of US adults (n 1030), survey responses were collected in 2018 and analysed in 2019.

First, 29–47 % of respondents incorrectly identified the healthier product from paired options, and respondents who self-identified as having difficulty in understanding labels were more likely to err. Second, for actual products composed primarily of refined grains, 43–51 % of respondents overstated the WG content, whereas for one product composed primarily of WG, 17 % of respondents understated the WG content.

The frequency of consumer misunderstanding of grain product labels was high in both study components. Potential policies to address consumer confusion include requiring disclosure of WG content as a percentage of total grain content or requiring disclosure of the grams of WG v. refined grains per serving.

To analyse disparities of malnutrition in all its forms by socio-economic indicators in children aged <5 years, adolescent girls and women of reproductive age (WRA).

We defined wasting/underweight, stunting/short stature, overweight and obesity following the WHO criteria for children aged <5 years, adolescents and WRA. We evaluated the prevalence of malnutrition by wealth status, education level and ethnicity (indigenous/non-indigenous).

Guatemalan 2014–2015 National Maternal and Child Health Survey.

Children aged <5 years (n 11 962), adolescent girls aged 15–19 years (n 1086) and WRA aged 20–49 years (n 11 354).

Stunting/short stature prevalence among children, adolescents and WRA was 2·8, 2·1 and 2·0 times higher in the poorest compared with the richest; 2·9, 2·9 and 2·1 times higher in the lower educational level than in the highest; and 1·7, 1·7 and 1·6 times higher in the indigenous than in the non-indigenous population. In contrast, overweight/obesity prevalence among children, adolescents and WRA was 1·6, 2·1 and 1·8 times higher in the richest compared with the poorest; 1·6, 1·3 and 1·3 times higher in the higher educational level than in the lowest; and 1·3, 1·7 and 1·3 times higher in the non-indigenous than in the indigenous population.

Stunting/short stature is more prevalent among low-income, low-education and indigenous populations in all age groups. In contrast, overweight/obesity is more prevalent in high-income, high-education and non-indigenous populations in all age groups. These outcomes demonstrate socio-economic and ethnic disparities for malnutrition in all its forms.

To determine the mediating effect of direct preschool and parent nutrition education on changes in skin carotenoids scores over 2 years in children of Mexican heritage.

In a quasi-experimental, community-based study, two school districts were randomly assigned to either a comparison group (parent workshops unrelated to nutrition) or a childhood obesity prevention intervention group which included nutrition education at family nights for parents and at school for children. Changes in skin carotenoid intensity scores (diffCAROT, year 2015 minus 2013) were measured in children as a proxy for fruit and vegetable consumption using Resonance Raman Spectroscopy.

Two rural, low-income, school districts from a county in California’s Central Valley.

316 Mexican heritage families with children aged 3–8 years.

Intervention group children improved over 2 years in skin carotenoid scores relative to comparison group children (diffCAROT mean +1419 (sd 9540) v. –3473 (sd 9272), P = 0·0001). Parent attendance at nutrition education classes partially mediated the intervention effect on diffCAROT (P = 0·02). Controlling for child’s age and other covariates, participation in preschool during the study had a significant positive effect on diffCAROT among intervention children compared with controls (P < 0·03), whereas no significant difference by group was observed among those not enrolled in preschool or already enrolled in elementary school.

Programmes that combine direct parent and preschool nutrition education may be effective in low-income Mexican heritage families to improve children’s intake of fruit and vegetables.

This study is a secondary data analysis that examines the association between parent modelling of dietary intake and physical activity and the same child behaviours among different races/ethnicities using innovative, rigorous and objective measures.

Ecological momentary assessment surveys were sent to parents to assess whether their child had seen them exercise or consume food. Dietary recall data and accelerometry were used to determine dietary intake and physical activity behaviours of children.

Participants were randomly selected from primary care clinics, serving low-income and racially/ethnically diverse families in Minnesota, USA.

Participants were families with children aged 5–7 years old who lived with parents 50 % of the time and shared at least one meal together.

A 10 percentage point higher prevalence in parent modelling of fruit and vegetable intake was associated with 0·12 higher serving intake of those same foods in children. The prevalence of parent modelling of eating energy dense foods (10 % prevalence units) was associated with 0·09 higher serving intake of sugar-sweetened beverages. Furthermore, accelerometry-measured parent sedentary hours was strongly correlated with child sedentary time (0·37 child sedentary hours per parent sedentary hours). An exploratory interaction analysis did not reveal any statistical evidence that these relationships depended on the child’s race/ethnic background.

Interventions that increase parent modelling of healthy eating and minimise modelling of energy dense foods may have favourable effects on child dietary quality. Additionally, future research is needed to clarify the associations of parent modelling of physical activity and children’s physical activity levels.

The objective was to examine the association between parenting practices, toddler’s dietary intake and BMI. In addition, potential moderation of these associations by general parenting and child temperament was examined.

The current cross-sectional study assessed parenting practices using the Comprehensive Feeding Practices Questionnaire, general parenting using the Comprehensive General Parenting Questionnaire, child temperament using the Child Behavior Check List, and children’s dietary intake through parental questionnaires. Children’s weight and length were objectively measured to determine BMI z-scores. Associations were examined using multiple linear regression analyses. Moderation was examined using interaction terms.

Home setting.

393 Dutch toddlers (age 1–3 years) and their parents recruited through fifty childcare centres and preschools in the Netherlands.

Various practices were related to children’s diet and BMI. For instance, the availability of healthy foods is the most important predictor of healthy dietary intake (e.g. β = –0·35 for sweets; β = 0·18 for fruit). The association of availability with a healthier diet was strongest when parents scored low on the positive parenting style dimensions, including nurturance, structure and/or behavioural control. In addition, it seemed that a high availability of healthy foods and low availability of unhealthy foods is especially beneficial for children showing withdrawal/depressive, anxious or overactive behaviour, while encouraging balance and variety is not beneficial for these children. All other practices were related to children’s diet and/or BMI as well.

The findings underline the importance of viewing the impact of parenting practices in the context of general parenting and child temperament.

Despite extensive research on framing effects in public health communication, there is still a lack of knowledge on how gain frames v. loss frames can encourage healthy eating behaviour among children.

Drawing on the Prospect Theory as well as on the Reactivity of Embedded Food Cues in Advertising Model, an experiment exposed children to an audio-visual cartoon movie with gain-framed nutritional messages about eating fruit (gain condition), loss-framed nutritional messages about eating fruit (loss condition) or a message without any food (control group). Children’s fruit intake was measured as the dependent variable. Children’s awareness of gain- and loss-framed arguments was treated as mediators, while children’s age and parents’ self-reported food-related mediation styles were modelled as moderators.

Vienna, Austria, in 2018.

Children aged 6–10 years (N 161).

Children in the gain frame group were more aware of gain-framed arguments, and children in the loss frame group were more aware of loss-framed arguments than those in the control group. However, only the mediator awareness of gain-framed arguments increased fruit intake. Additionally, there was a direct effect of the gain-framed message on fruit intake compared to the control group. The loss condition did not reveal such an effect. Neither parent’s food-related mediation styles nor children’s age moderated those results.

Gain-framing seems to be more effective in influencing children’s healthy food choices compared to loss-framing. Implications for health communication strategies aimed at children are discussed.

To determine the association between excess body fat, assessed by skinfold thickness, and the incidence of type 2 diabetes mellitus (T2DM) and hypertension (HT).

Data from the ongoing PERU MIGRANT Study were analysed. The outcomes were T2DM and HT, and the exposure was skinfold thickness measured in bicipital, tricipital, subscapular and suprailiac areas. The Durnin–Womersley formula and SIRI equation were used for body fat percentage estimation. Risk ratios and population attributable fractions (PAF) were calculated using Poisson regression.

Rural (Ayacucho) and urban shantytown district (San Juan de Miraflores, Lima) in Peru.

Adults (n 988) aged ≥30 years (rural, rural-to-urban migrants, urban) completed the baseline study. A total of 785 and 690 were included in T2DM and HT incidence analysis, respectively.

At baseline, age mean was 48·0 (sd 12·0) years and 47 % were males. For T2DM, in 7·6 (sd 1·3) years, sixty-one new cases were identified, overall incidence of 1·0 (95 % CI 0·8, 1·3) per 100 person-years. Bicipital and subscapular skinfolds were associated with 2·8-fold and 6·4-fold risk of developing T2DM. On the other hand, in 6·5 (sd 2·5) years, overall incidence of HT was 2·6 (95 % CI 2·2, 3·1) per 100 person-years. Subscapular and overall fat obesity were associated with 2·4- and 2·9-fold risk for developing HT. The PAF for subscapular skinfold was 73·6 and 39·2 % for T2DM and HT, respectively.

We found a strong association between subscapular skinfold thickness and developing T2DM and HT. Skinfold assessment can be a laboratory-free strategy to identify high-risk HT and T2DM cases.
