Advertising ultra-processed foods around urban and rural schools in Kenya
Marketing of ultra-processed foods (UPFs) can influence children’s food preferences and consumption patterns. However, limited data exist on the extent and nature of UPF marketing around schools in low- and middle-income countries, including Kenya. This study assessed the extent, type, and content of food and beverage advertising near schools in urban and rural settings in Kenya. We conducted a cross-sectional study in June–July 2021 across three…
How Children's Experiences and Perceptions of Their School Food Environment Influence Their Food‐Related Decisions In‐School in Urban Ghana
School food environments play an important role in shaping children's food-related decisions, including where and what foods to acquire and consume on a school day. In Ghana, evidence indicates that food environments in and around schools may limit healthy food acquisition and consumption behaviour. This study aimed to understand how children's experiences and perceptions of their school food environment influence food acquisition and consumption…
Understanding the Decentralised School Food Procurement Model in Ghana Through the Lens of School Caterers
The Ghana School Feeding Programme (GFSP) operates a decentralised procurement model, in which school caterers are responsible for: selecting, purchasing, transporting, preparing, delivering and distributing school meals. However, caterers' views and experiences are rarely taken into account. This study aimed to better understand GSFP caterers' lived professional experience to identify context-specific challenges and solutions around their food p…

Gender‐linked differences in everyday memory performance
Recent research has demonstrated that people hold beliefs about how well others perform everyday memory tasks according to another's sex. For example, meta‐memory ratings indicate that other men and other women are believed to differ in their success at performing certain memory tasks (Crawford, Herrmann, Holdsworth, Randall & Robbins, 1989). In the present study, two experiments investigated whether gender stereotypes concerning everyday memory …

Meal patterns and cooking practices in Southern France and Central England
Some of the study's findings confirm popular stereotypes of French and English food cultures, as the importance of the convivial aspects of eating, as well as more traditional practices such as cooking meals from basic ingredients, structured mealtimes and less between-meal snacking, remain more prominent within the French population. This may contribute to the differences in prevalence of obesity seen between the two countries

Perceptions of healthy weight of Malians and Moroccans living in different geographical environments Michelle Holdsworth
Objectives Perceptions of body size can influence whether obesity is seen as desirable and therefore whether a population is motivated to change. Few studies have investigated the effect of migration and living in different environments on preferences for body size. The present study examined body size preferences and satisfaction of adults living in urban and rural Morocco and Mali, as well as of migrants to France from these countries, to inves…
Deprivation, clubs and drugs
A large proportion of individuals report having used weight management strategies. Slimming clubs and over-the-counter weight loss medication account for a smaller proportion of the overall uptake. Those from less deprived areas were more likely to use slimming clubs while those from more deprived areas were more likely to use weight-loss medications. Future NHS and Local Authority commissioning of weight management services must be aware of this…
The relevance of the side-view in body image scales for public health
Variation in body shape assessed by several bio-anthropometrics related to health and nutritional status was larger for side than front body outlines. Integrating side views in body size scales would improve the accuracy of body size assessment and thus, the assessment of behaviours leading to overweight, as well as symptoms of body image disturbances, in Africa and potentially in other populations
