This study examined drivers and barriers to iron and folic acid supplementation and consumption of iron- and vitamin A-rich foods among women of reproductive age and adolescent girls in Niger.

This was an exploratory qualitative study using focus group discussions and semi-structured interviews.

This study was conducted in the rural areas of three districts in Maradi and Zinder regions of southern Niger.

The study included a purposive sample of 56 WRA (15–49 years), 34 non-pregnant adolescent girls (10–14 years), 105 family members and community leaders, 32 health workers and 12 national and regional level stakeholders.

Respondents demonstrated widespread knowledge of recommendations for iron and folic acid during pregnancy and had positive attitudes towards supplements. However, supply barriers were significant, and adherence was limited by side effects, among other constraints. Despite knowledge about and positive attitudes towards micronutrient-source foods, respondents reported that limited food access was an overriding constraint to increasing consumption. Women of reproductive age were seen as nutritionally vulnerable; however, husbands were often not able to provide sufficient nutritious food, and there was a cultural expectation that wives serve themselves food last. Adolescent girls were not seen as nutritionally vulnerable, and there was little family support for their consumption of nutritious foods.

Projects should work with local actors to develop multi-pronged solutions that address supply and access barriers for iron and folic acid and micronutrient-rich foods and to improve social support for nutrition.

The study sought to assess the influence of nutrition education and intervention programmes on nutrition knowledge and dietary practice among both students and staff (including faculty) of Princess Nourah Bint Abdulrahman University in Saudi Arabia.

A pretest–posttest, non-randomised experimental study design was implemented at Princess Nourah Bint Abdulrahman University in Riyadh City between September 2019 and February 2020.

Princess Nourah Bint Abdulrahman University is the largest women’s university in the world and has eighteen colleges and institutions and around ninety academic programmes.

The survey was completed by 1824 participants (1350 students and 474 staff/faculty) before the intervention and by a different cohort of 1731 participants (1317 students and 414 staff/faculty) after the intervention. In total, an independent sample of 3555 staff and students participated. Participants were asked about dietary knowledge and practices. Dietary knowledge entailed food variety and nutrients, fast food and its poor nutritional value, and the influence of cooking style on the nutritional quality of food. Dietary practices involved eating breakfast; consuming salt/sugar, eating high-salt food; eating pre-packaged food and consumption of vegetables, fruits, supplements, water and caffeine.

The majority of the sample consisted of students (75·1 %) and had not been diagnosed with any disease (73·7 %). The result of the current study showed that nutrition knowledge improved after completion of the nutrition programme.

The nutrition awareness programme improved students’ nutritional knowledge; however, there was no significant effect on their dietary practices. Future nutrition awareness programmes should separate activities for students and staff, focusing on one target population at a time.

To synthesise evidence of urban dietary behaviours (macronutrients, types of foods, dietary diversity and dietary practices) in two African countries in relation to postulated changes in the context of nutrition transition.

Systematic review and meta-analyses, including six online databases and grey literature, 1971–2018 (Protocol CRD42017067718).

Population-based studies of healthy adolescents and adults.

The forty-seven included studies encompassed 20 726 individuals plus 6526 households. Macronutrients were within WHO-recommended ranges: mean energy intake was 1867 kcal/d (95 % CI 1764, 1969) and the proportions of macronutrients were carbohydrate 61·2 % (58·4, 64·0), fat 25·3 % (22·8, 28·0) and protein 13·7 % (12·3, 15·1). The proportion of population consuming fruit and vegetables was 51·6 %; unhealthy foods, 29·4 %; and sugar-sweetened beverages (SSBs), 39·9 %. Two-thirds (68·8 %) consumed animal-source proteins. Dietary diversity scores were within the mid-range. Meal patterns were structured (typically three meals per day), with evidence lacking on snacking or eating out.

Population-level diets fell within WHO macronutrient recommendations, were relatively diverse with structured meal patterns, but some indications of nutrition transition were apparent. The proportion of population consuming fruit and vegetables was low compared to healthy-eating recommendations, and consumption of SSBs was widespread. A paucity of evidence from 1971 to 2010 precluded a longitudinal analysis of nutrition transition. Evidence from these two countries indicates which aspects of dietary behaviours may be contributing to increasing overweight/obesity, namely a low proportion of population consuming fruit and vegetables and widespread consumption of SSBs. These are potential targets for promoting healthier diets.

To assess the nutritional status and dietary practices of 0–24-month-old children living in Brazilian Amazonia.

Cross-sectional study. Information on children’s dietary intakes was obtained from diet history data. Weight and length were measured for anthropometric evaluation. Fe status was assessed using fasting venous blood samples; Hb, serum ferritin and soluble transferrin receptor concentrations were measured.

The towns of Assis Brasil and Acrelândia in the state of Acre, north-west Brazil.

A total of sixty-nine randomly selected 0–24-month-old children.

Of these children, 40·3 % were anaemic, 63·1 % were Fe-deficient, 28·1 % had Fe-deficiency anaemia and 11·6 % were stunted. Breast-feeding was initiated by 97·1 % of mothers, followed by early feeding with complementary foods. The dietary pattern reflected a high intake of carbohydrate-rich foods and cow’s milk, with irregular intakes of fruit, vegetables and meat. All infants and 92·3 % of toddlers were at risk of inadequate Fe intakes. Fe from animal foods contributed on average 0·5 % and 14·3 % to total dietary Fe intake among infants and toddlers, respectively.

Poor nutritional status and inadequate feeding practices in this study population reinforce the importance of exclusive breast-feeding during the first 6 months of life. Greater emphasis is required to improve the bioavailability of dietary Fe during complementary feeding practices.
