Trends and future projections of the prevalence of adult obesity in Saudi Arabia, 1992-2022

Abstract

The prevalence of obesity among adults in Saudi Arabia increased from 22% in 1990-1993 to 36% in 2005, and future projections of the prevalence of adult obesity are needed by health policy-makers. In a secondary analysis of published data, a number of assumptions were applied to estimate the trends and projections in the age-and sex-specific prevalence of adult obesity in Saudi Arabia over the period 1992-2022. Five studies conducted between 1989 and 2005 were eligible for inclusion, using body mass index (BMI) ≥ 30 kg/m(2) to define obesity. The overall prevalence of obesity was projected to increase from around 12% in 1992 to 41% by 2022 in men, and from 21% to 78% in women. Women had much higher projected prevalence than men, particularly in the age groups 35-44, 45-54 and 55-64 years. Effective national strategies are needed to reduce or halt the projected rise in obesity prevalence.
