Diet Culture and Obesity in Northern Africa

Abstract

The etiology of obesity in North Africa is not well understood and few studies shed any light on its development among women. This study compiles what is known about the prevalence of obesity and its determinants in Morocco and Tunisia. Results from the authors' two surveys on nutrition-related disease among reproductive-age women (sample size: 2800) and their children (1200 children under 5 y and 500 adolescents) were combined with data from four national income and expenditure surveys (dating from 1980) to assess obesity trends and development in Morocco and Tunisia. Overall levels of obesity, identified by body mass index (BMI) > or = 30 kg/m(2), were 12.2% in Morocco and 14.4% in Tunisia. Obesity is significantly higher among women than among men in both countries (22.7% vs. 6.7% in Tunisia and 18% vs. 5.7% in Morocco) and prevalence among women has tripled over the past 20 y. Half of all women are overweight or obese (BMI > 25) with 50.9% in Tunisia and 51.3% in Morocco. Overweight increases with age and seems to take hold in adolescence, particularly among girls. In Tunisia, 9.1% of adolescent girls are at risk for being overweight (BMI/age > or = 85th percentile). Prevalence of overweight and obesity are greater for women in urban areas and with lower education levels. Obese women in both countries take in significantly more calories and macronutrients than normal-weight women. The percentage contribution to calories from fat, protein and carbohydrates seems to be within normal limits, whereas fat intake is high (31%) in Tunisia and carbohydrate intake (65-67%) is high in Morocco. These are alarming trends for public health professionals and policy makers in countries still grappling with the public health effects of malnutrition and micronutrient deficiencies. Health institutions in these countries have an enormous challenge to change cultural norms that do not recognize obesity, to prevent significant damage to the public's health from obesity.

Social and dietary determinants of body mass index of adult Jamaicans of African origin

“…The mean BMIs of men and women were similar to averages reported in some Caribbean countries but lower than in others, and in the USA (Cooper et al, 1997). High prevalence of obesity in women surpassed the levels reported in other developing countries in Latin America (Martorell et al, 2000) and Africa (Martorell et al, 2000;Mokhtar et al, 2001). Of interest, in our international study (Mbanya et al, 1999;Cruickshank et al, 2001), 35% of Afro-Caribbean women in Britain were obese, as were 37% of women in Pomerleau et al's (1999) study.…”

Review of the nutrition situation in the Eastern Mediterranean Region

“…The results highlight a high prevalence and increasing trend of adult obesity in many countries (44,(87)(88)(89)(90). The regional average of adult obesity (24%) exceeds the worldwide average (9.8% in men and 13.8% in women) (142), as well as estimates reported from South Asia (1.2-2.9%), but it is lower than the average prevalence of adult obesity in North America (29.2%) (142).…”

“…Available data suggest an increasing secular trend in the prevalence of adult obesity in most countries of the Region. This trend was more pronounced in countries such as the UAE (88,89), Tunisia (90,91), Afghanistan (44), Kuwait (92), Bahrain (78,93) and Lebanon (93).…”
