In the context of the nutrition transition and associated changes in the food retail sector, to examine the socio-economic characteristics and motivations of shoppers using different retail formats (large supermarkets (LSM), medium-sized supermarkets (MSM) or traditional outlets) in Tunisia.
Cross-sectional survey (2006). Socio-economic status, type of food retailer and motivations data were collected during house visits. Associations between socio-economic factors and type of retailer were assessed by multinomial regression; correspondence analysis was used to analyse declared motivations.
Peri-urban area around Tunis, Tunisia, North Africa.
Clustered random sample of 724 households.
One-third of the households used LSM, two-thirds used either type of supermarket, but less than 5 % used supermarkets only. Those who shopped for food at supermarkets were of higher socio-economic status; those who used LSM were much wealthier, more often had a steady income or owned a credit card, while MSM users were more urban and had a higher level of education. Most households still frequently used traditional outlets, mostly their neighbourhood grocer. Reasons given for shopping at the different retailers were most markedly leisure for LSM, while for the neighbourhood grocer the reasons were fidelity, proximity and availability of credit (the latter even more for lower-income customers).
The results pertain to the transition in food shopping practices in a south Mediterranean country; they should be considered in the context of growing inequalities in health linked to the nutritional transition, as they differentiate use and motivations for the choice of supermarkets v. traditional food retailers according to socio-economic status.
To study how dietary patterns and physical activity vary with acculturation and with past and current exposure to socio-cultural norms of the home country among Tunisian migrants.
A retrospective cohort study was conducted using quota sampling (n 150) based on age and residence. Dietary intake was assessed using a validated FFQ. Physical activity level and dietary aspects were compared according to length of residence (acculturation), age at migration (past exposure) and social ties with the home country (current exposure).
Subjects and setting
Tunisian migrant men residing in the South of France.
Migrants who had lived in France for more than 9 years had a higher percentage contribution of meat to energy intake (P = 0·04), a higher Na intake (P = 0·04), a lower percentage contribution of sugar and sweets (P = 0·04) and a lower percentage of carbohydrates (P = 0·03) than short-term migrants. Men who migrated before 21 years of age had a higher Na intake than ‘late’ migrants (P = 0·02). Men who had distant social ties with Tunisia had a lower physical activity level (P = 0·01) whereas men who had close ties had a higher percentage of fat (P = 0·01) and a higher ratio of MUFA to SFA (P = 0·02).
Acculturation led to a convergence of some characteristics to those of the host population, while some results (meat and salt consumption) were at variance with other acculturation studies. Past and current exposure to the home country helped maintain some positive aspects of the diet. Nevertheless, present dietary changes in Tunisia could soon lessen these features.
To assess the nutritional status of Tunisian adolescents and associated factors.
A cross-sectional study based on a national stratified random cluster sample.
Subjects and methods
In all, 1295 boys and 1577 girls aged 15–19 years, of whom 28·4 % had already left school. Socio-economic characteristics of the parents, anthropometric measurements, food behaviours and physical activity of the adolescents were recorded during home visits.
Prevalence of underweight, overweight and obesity (WHO/National Center for Health Statistics reference) were, respectively, 8·1 %, 17·4 % and 4·1 % among boys and 1·3 %, 20·7 % and 4·4 % among girls; abdominal obesity was highly prevalent among both sexes. Prevalence of overweight differed by region (from 11·5 % to 22·2 %) and was higher in urban v. rural areas for males (21·7 % v. 10·4 %) but not for females (21·7 % v. 19·2 %). These differences were partially mediated by socio-economic and lifestyle factors for males. For females, influence of cultural factors is hypothesised. In rural areas, overweight was more prevalent among boys of higher economic level households, having a working mother or a sedentary lifestyle; for girls, prevalence increased with the level of education of the mother. In urban areas, prevalence of overweight was related to eating habits: it was higher for boys with irregular snacking habits and for girls skipping daily meals. Urban girls having left school were also more overweight.
Overweight and abdominal obesity in late adolescence have become a true public health problem in Tunisia with the combined effects of cultural tradition for girls in rural areas, and of rapid economic development for boys and girls in cities.
To assess knowledge of dietary and behaviour-related determinants of non-communicable disease (NCD) of urban Senegalese women.
A cross-sectional, population study using an interviewer-administered knowledge questionnaire, developed and validated for this study. The questionnaire consisted of 24 items with six scores measuring knowledge of: (1) diet- and behaviour-related causes of NCD; (2) diet quality–NCD relationship; (3) fruit and vegetable link with NCD; (4) health consequences of obesity; (5) causes of cardiovascular disease (CVD); and (6) causes of certain cancers.
A random sample of 301 women aged 20–50 years.
The knowledge scores developed suggest that the health consequences of obesity (mean score of 65.4%) were best understood followed by causes of CVD (mean score of 60.6%), because obesity, smoking, high blood cholesterol and dietary fat were well recognised as risk factors for CVD. Subjects scored least for their knowledge of the protective effect of fruit and vegetables (mean score of 19.9%). Knowledge of causes of certain cancers (mean score of 36.1%) was also low. Women who worked outside the home had better knowledge for two scores but otherwise no relationship was found between knowledge and literacy, formal education or body mass index.
Findings suggest reasonable overall knowledge concerning diet and behaviour with NCD, especially given the relatively new context of the obesity epidemic in Senegal. However, there was poor knowledge of the benefit of eating fruit and vegetables and other preventable causes of certain cancers. Education targeting the benefits of vegetables and fruit may have the greatest impact on NCD prevention.
