To assess trends in nutrient intakes and nutritional status of rural adult women (≥18–60 years) and the association of sociodemographic characteristics with overweight/obesity.

Community-based cross-sectional studies carried out during 1975–79 to 2011–12 by the National Nutrition Monitoring Bureau (NNMB) were used. Anthropometric measurements such as height, weight and waist circumference, carried out during the surveys, were used. Association and logistic regression analyses between sociodemographic characteristics and overweight/obesity and abdominal obesity were conducted using a complex samples procedure.

Ten NNMB states of India.

Non-pregnant and non-lactating rural women aged ≥18–60 years covered during the above periods from ten states in India.

The prevalence of chronic energy deficiency has declined from 52 % during 1975–79 to 34 % during 2011–12, while that of overweight/obesity has increased from 7 % to 24 % during the same period. Median intakes of most of the nutrients have increased over the same period, although they were below recommended levels. The chance of overweight/obesity and abdominal obesity was significantly (P<0·01) higher among women aged 40–60 years, those belonging to Christian religion and other backward communities, women living in pucca houses, literate women, women engaged in service and business, and those having higher per capita income.

Prevalence of chronic energy deficiency has declined significantly; however, overweight/obesity has increased during the same period. This increase in overweight/obesity may be attributed to increased consumption of fatty foods, sedentary lifestyle and improved socio-economic status. There is a need to educate the community about regular physical exercise, low intakes of fats and oils, and a balanced diet.

To revisit seasonality by assessing how household diets vary across agricultural seasons in rural and urban Ethiopia. The role of seasonality on the sources and intake of energy (per capita) and household dietary diversity score (HDDS) was analysed.

The use of nationally representative household-level data collected each month over one year to study the seasonal changes in the sources and intake of energy and HDDS.

Eleven regions of Ethiopia, including rural and urban settings.

Total of 27 835 households were interviewed between July 2010 and July 2011 in all eleven regions of the country. On average each month saw 2300 household interviews, yielding nationally representative data for each calendar month.

For rural households, the mean daily per capita energy intake was 10 288 kJ (2459 kcal) in February (post-harvest period) and lower in the lean season: 9703 kJ (2319 kcal) in June (P<0·05) and 9552 kJ (2283 kcal) in July (P<0·001). HDDS for rural households was highest in February (6·73) and lowest in June (5·98; P<0·001) but high again in July (6·57). Urban energy intake was also lower in the lean season but HDDS varied less by season. Considerable seasonal variation was also found in energy sources in rural areas, less so in urban areas.

Household diets in Ethiopia remain subjected to significant seasonal stress. HDDS and food security measured using energy intake do not always agree. Preferably, HDDS and energy intake data should be used together to assess food security.

China’s internal migration has left 61 million children living apart from their parent(s) in rural areas. The present study aimed to examine whether the relative contributions of macronutrients (protein, fat and carbohydrate) to total energy intake differ between children left behind by the father or mother, compared with children from intact families.

Drawing on a longitudinal study, the China Health and Nutrition Survey (1997–2009), multilevel modelling analyses (level 1: occasions; level 2: children; level 3: villages) were performed.

Data from rural communities in nine provinces in China.

Rural children (n 975; 555 boys and 420 girls) from 140 villages.

Among boys of school age, being left behind by the father tended to reduce the relative protein intake by 0·70 % (P<0·01) compared with boys from intact families. Being left behind by at least the mother was more detrimental for young boys under the age of 6 years than paternal migration, reducing relative protein intake by 1·14 % (P<0·05). Parental migration was associated with a significant increase in young boys’ relative fat intake by 2·60 % (P<0·05). No significant associations were found for girls. Results suggest left-behind boys, especially in early life, are subject to a higher-fat and lower-protein diet compared with non-left-behind boys. This may put them at increased risk of being overweight or obese, or of suffering from stunted growth, when they grow up.

Public health policies should recognise the influences of parental migration on boys, especially maternal migration, and encourage a more balanced diet for children in rural China.

To evaluate the Canadian Diet History Questionnaire I (C-DHQ I) food list and to adapt the US DHQ II for Canada using Canadian dietary survey data.

Twenty-four-hour dietary recalls reported by adults in a national Canadian survey were analysed to create a food list corresponding to C-DHQ I food questions. The percentage contribution of the food list to the total survey intake of seventeen nutrients was used as the criterion to evaluate the suitability of the C-DHQ I to capture food intake in Canadian populations. The data were also analysed to identify foods and to modify portion sizes for the C-DHQ II.

The Canadian Community Health Survey (CCHS) – Cycle 2.2 Nutrition (2004).

Adults (n 20 159) who completed 24 h dietary recalls during in-person interviews.

Four thousand five hundred and thirty-three foods and recipes were grouped into 268 Food Groups, of which 212 corresponded to questions on the C-DHQ I. Nutrient intakes captured by the C-DHQ I ranged from 79 % for fat to 100 % for alcohol. For the new C-DHQ II, some food questions were retained from the original US DHQ II while others were added based on foods reported in CCHS and foods available on the Canadian market since 2004. Of 153 questions, 143 were associated with portion sizes of which fifty-three were modified from US values. Sex-specific nutrient profiles for the C-DHQ II nutrient database were derived using CCHS data.

The C-DHQ I and II are designed to optimize the capture of foods consumed by Canadian populations.

We aimed to evaluate the DHA and arachidonic acid (AA) levels in human breast milk worldwide by country, region and socio-economic status.

Descriptive review conducted on English publications reporting breast-milk DHA and AA levels.

We systematically searched and identified eligible literature in PubMed from January 1980 to July 2015. Data on breast-milk DHA and AA levels from women who had given birth to term infants were included.

Seventy-eight studies from forty-one countries were included with 4163 breast-milk samples of 3746 individuals.

Worldwide mean levels of DHA and AA in breast milk were 0·37 (sd 0·11) % and 0·55 (sd 0·14) % of total fatty acids, respectively. The breast-milk DHA levels from women with accessibility to marine foods were significantly higher than those from women without accessibility (0·35 (sd 0·20) % v. 0·25 (sd 0·14) %, P<0·05). Data from the Asian region showed the highest DHA concentration but much lower AA concentration in breast milk compared with all other regions, independent of accessibility to marine foods. Comparison was made among Canada, Poland and Japan – three typical countries (each with sample size of more than 100 women) from different regions but all with high income and similar accessibility to fish/marine foods.

The current review provides an update on worldwide variation in breast-milk DHA and AA levels and underlines the need for future population- or region-specific investigations.

Simple, cost-effective and convenient instruments like food group-based scores are proposed to assess micronutrient adequacy of children in developing countries. We assessed the predictive ability and seasonal stability of a dietary diversity score (DDS) to indicate dietary quality of infants.

A 24 h dietary recall assessment was carried out on a sample of 320 and 312 breast-fed infants aged 6–12 months during harvest (HS) and pre-harvest (PHS) seasons, respectively, in Ethiopia. DDS was calculated based on seven food groups, while mean micronutrient density adequacy (MMDA) was calculated for eight micronutrients. Multiple linear regression models were used to assess the relationship between DDS and MMDA, and differences in nutrient intake between the two seasons. A receiver-operating characteristic curve analysis was performed to derive DDS cut-offs that maximized sensitivity and specificity of assessing dietary quality.

The study was conducted in the catchment of the Gilgel Gibe Field Research Centre of Jimma University, south-west Ethiopia.

The mean (sd) DDS for HS and PHS was 2·1 (0·94) and 2·3 (1·1), respectively. The DDS was associated with MMDA (β=0·045, P<0·0001 in HS; β=0·044, P<0001 in PHS). A DDS of ≤2 food groups best predicted ‘low’ MMDA (<50 %) with 84 % and 92 % sensitivity, 36 % and 43 % specificity, and 47 % and 51 % correct classification for the HS and PHS, respectively.

DDS is predictive of dietary quality of breast-fed infants. The study supports the use of DDS to indicate inadequate intakes of micronutrients by breast-fed infants in different seasons.

To assess and compare the nutrition environment and practices (as they relate to pre-schoolers) of centre- and home-based child-care facilities.

Using a cross-sectional study design, nineteen child-care facilities (ten centre-based, nine home-based) were assessed for one full day using the Environment and Policy Assessment and Observation (EPAO) tool (consisting of a day-long observation/review of the nutrition environment, practices and related documents). Specifically, eight nutrition-related subscales were considered.

Child-care facilities in London, Ontario, Canada.

Child-care facilities were recruited through directors at centre-based programmes and the providers of home-based programmes.

The mean total nutrition environment EPAO scores for centre- and home-based facilities were 12·3 (sd 1·94) and 10·8 (sd 0·78) out of 20 (where a higher score indicates a more supportive environment with regard to nutrition), respectively. The difference between the total nutrition environment EPAO score for centre- and home-based facilities was approaching significance (P=0·055). For both types of facilities, the highest nutrition subscale score (out of 20) was achieved in the staff behaviours domain (centre mean=17·4; home mean=17·0) and the lowest was in the nutrition training and education domain (centre mean=3·6; home mean=2·0).

Additional research is needed to confirm these findings. In order to better support child-care staff and enhance the overall nutrition environment in child care, modifications to food practices could be adopted. Specifically, the nutritional quality of foods/beverages provided to pre-schoolers could be improved, nutrition-related training for child-care staff could be provided, and a nutrition curriculum could be created to educate pre-schoolers about healthy food choices.

The present study aimed to investigate the prevalence of metabolic syndrome (MetS) in 7- to 17-year-old children and adolescents in China and to examine the relationship between MetS and its associated early-life factors.

Data were collected using a standard parent/guardian questionnaire in a face-to-face interview. Each participant underwent a complete anthropometric evaluation. MetS was defined according to the criteria of the International Diabetes Federation (IDF; 2007) for children and adolescents.

Guangzhou, a large city in South China, September 2013.

A total of 1770 children and adolescents were enrolled in the study, including 913 girls (51·6 %) and 857 boys (48·4 %).

The overall prevalence of MetS in children and adolescents was 1·1 % (n 19), which was higher in boys (1·4 %) than in girls (0·8 %). Multivariate analysis indicated that high birth weight was significantly associated with abdominal obesity (OR=2·86; 95 % CI 1·62, 5·06) and MetS (OR=3·61; 95 % CI 1·33, 9·82). Furthermore, >6 months of maternal breast-feeding was inversely associated with MetS (OR=0·39; 95 % CI 0·16, 0·98).

Based on IDF criteria, the prevalence of MetS among southern Chinese children was significantly lower than that in other populations. High birth weight was significantly associated with abdominal obesity and MetS, and breast-feeding for longer than 6 months was inversely associated with MetS in South China.

Despite documented associations between stunting and cognitive development, few population-level studies have measured both indicators in individual children or assessed stunting’s associations with other developmental domains.

Meta-analysis using publicly available data from fifteen Multiple Indicator Cluster Surveys (MICS-4) to assess the association between stunting and development, controlling for maternal education, family wealth, books in the home, developmentally supportive parenting and sex of the child, stratified by country prevalence of breast-feeding (‘low BF’<90 %, ‘high BF’ ≥90 %). Ten-item Early Childhood Development Index (ECDI) scores assessed physical, learning, literacy/numeracy and socio-emotional developmental domains. Children on track in three or four domains were considered ‘on-track’ overall.

Fifteen low- and middle-income countries.

Publically available data from 58 513 children aged 36–59 months.

Severe stunting (height-for-age Z-score <−3) was negatively associated with on-track development (OR=0·75; 95 % CI 0·67, 0·83). Any stunting (Z-score <−2) was negatively associated with on-track development in countries with high BF prevalence (OR=0·82; 95 % CI 0·75, 0·89). Severe and any stunting were negatively associated with physical development (OR=0·77; 95 % CI 0·66, 0·89 and OR=0·82; 95 % CI 0·74, 0·91, respectively) and literacy/numeracy development in high BF countries (OR=0·45; 95 % CI 0·38, 0·53 and OR=0·59, 95 % CI 0·51, 0·68, respectively), but not low BF countries (OR=0·93; 95 % CI 0·70, 1·23 and OR=0·95, 95 % CI 0·79, 1·12, respectively). Any stunting was negatively associated with learning (OR=0·79; 95 % CI 0·72, 0·88). There was no clear association between stunting and socio-emotional development.

Stunting is associated with many but not all developmental domains across a diversity of countries and cultures. However, associations varied by country breast-feeding prevalence and developmental domain.

To describe nutrition environments in formal child care for 3- and 4-year-olds.

Cross-sectional online survey of nutrition-related child-care policy and practice. Written nutrition policies were analysed using the Wellness Child Care Assessment Tool.

Licensed child-care services in the Auckland, Counties Manukau and Waikato regions of New Zealand.

Eight hundred and forty-seven services (private and community day care, kindergartens and playcentres).

Managers/head teachers of 257 child-care services completed the survey. Of services, 82·4 % had a written food, nutrition or wellness policy. Most policies did not refer to the national Food and Nutrition Guidelines and lacked directives for staff regarding recommended behaviours to promote healthy eating. Food was provided daily to children in 56·4 % of child-care services, including 33·5 % that provided lunch and at least two other meals/snacks every day. Teachers talked to children about food, and cooked with children, at least weekly in 60 % of child-care services. Nearly all services had an edible garden (89·5 %). Foods/beverages were sold for fundraising in the past 12 months by 37·2 % of services. The most commonly reported barrier to promoting nutrition was a lack of support from families (20·6 %).

Although the majority of child-care services had a written nutrition policy, these were not comprehensive and contained weak statements that could be difficult to action. Foods served at celebrations and for fundraising were largely high in sugar, salt and/or saturated fat. Most services promoted some healthy eating behaviours but other widespread practices encouraged children to overeat or form unhealthy food preferences.

To estimate the effect of increased sugar-sweetened beverage (SSB) consumption on future adult obesity prevalence in South Africa in the absence of preventive measures.

A model was constructed to simulate the effect of a 2·4 % annual increase in SSB consumption on obesity prevalence. The model computed the change in energy intake assuming a compounding increase in SSB consumption. The population distribution of BMI by age and sex was modelled by fitting measured data from the 2012 South African National Income Dynamics Survey to the log-normal distribution and shifting the mean values.

Over the past decade the prevalence of obesity and related non-communicable diseases has increased in South Africa, as have the sales and availability of SSB. Soft drink sales in South Africa are projected to grow between 2012 and 2017 at an annual compounded growth rate of 2·4 % in the absence of preventive measures to curb consumption.

A 2·4 % annual growth in SSB sales alongside population growth and ageing will result in an additional 1 287 000 obese adults in South Africa by 2017, 22 % of which will be due to increased SSB consumption.

In order to meet the South African target of reducing the number of people who are obese and/or overweight by 10 % by 2020, the country cannot afford to delay implementing effective population-wide interventions. In the face of plans to increase growth of SSB, the country will soon face even greater challenges in overcoming obesity and related non-communicable diseases.

To undertake a systematic review to determine similarities and differences in metrics and results between recently and/or currently used tools, protocols and methods for monitoring Australian healthy food prices and affordability.

Electronic databases of peer-reviewed literature and online grey literature were systematically searched using the PRISMA approach for articles and reports relating to healthy food and diet price assessment tools, protocols, methods and results that utilised retail pricing.

National, state, regional and local areas of Australia from 1995 to 2015.

Assessment tools, protocols and methods to measure the price of ‘healthy’ foods and diets.

The search identified fifty-nine discrete surveys of ‘healthy’ food pricing incorporating six major food pricing tools (those used in multiple areas and time periods) and five minor food pricing tools (those used in a single survey area or time period). Analysis demonstrated methodological differences regarding: included foods; reference households; use of availability and/or quality measures; household income sources; store sampling methods; data collection protocols; analysis methods; and results.

‘Healthy’ food price assessment methods used in Australia lack comparability across all metrics and most do not fully align with a ‘healthy’ diet as recommended by the current Australian Dietary Guidelines. None have been applied nationally. Assessment of the price, price differential and affordability of healthy (recommended) and current (unhealthy) diets would provide more robust and meaningful data to inform health and fiscal policy in Australia. The INFORMAS ‘optimal’ approach provides a potential framework for development of these methods.
