Nutrition in Context: Evidence, Equity, and Accountability in Public Health Nutrition
Public health nutrition is shaped by the environments in which people obtain food, make dietary choices, experience nutritional vulnerability, and respond to changing health and social conditions.This third issue of Volume 17 of World Nutrition brings together 21 contributions spanning original research, reviews, commentaries, opinion, and policy perspectives, reflecting the breadth and interconnectedness of contemporary nutrition challenges.Collectively, these contributions emphasise the importance of context, equity, accountability, and evidence-informed action in improving nutrition and health outcomes.A prominent theme is the food environment and the accountability of institutions that influence dietary choices.Sezaki et al., in Access to Nutrition Initiative Global Index and Spotlight Index comparisons: Promoting nation-led frameworks for nutrition accountability, examine the evolution of corporate nutrition accountability frameworks and the growing role of country-specific approaches.Complementing this work, du Plessis et al., in Food and non-alcoholic beverage marketing and sponsorship at secondary schools in the City of Cape Town, South Africa, document extensive food and beverage marketing within schools.Riofrio Jacinto et al., in Food access, purchasing habits, and dietary diversity of peri-urban households in Hanoi, Vietnam, further demonstrate how purchasing behaviour, affordability, proximity, and food assortment can shape dietary diversity.Together, these studies illustrate why nutrition policy must consider not only individual choices but also the environments in which those choices are made.The issue gives considerable attention to nutrition across the life course.Ali et al., in From Breast to Bowl: A quasi-experimental, mixed-methods evaluation of peer learning to improve complementary feeding in rural northeastern Ghana, demonstrate the potential of peer learning to strengthen complementary feeding practices.Kamda et al., in Factors associated with diet adequacy among women attending antenatal care in the conflict-affected Kumba Municipalities, Cameroon, examine the nutritional vulnerabilities women experience in conflict-affected settings.Funduluka et al., in Unveiling dietary patterns among children aged 6-23 months: A framework analysis for perspectives in Chinyunyu Community, Rufunsa District, Zambia, identify poverty, household decision-making, workload, and food availability as important influences on infant and young child feeding.Pencil et al., in Anaemia among in-school adolescents from Harare, Zimbabwe: Prevalence and key drivers, highlight the burden of anaemia among adolescents and the relevance of household education, nutrition knowledge, and dietary practices.Onyeanwu, in Food insecurity among older adults in the United States: A systematic review through the gerontological public health framework, extends attention to older adults, highlighting the interconnected economic, social, environmental, and healthcare determinants of food insecurity and its consequences.
