Prevalence of obesity in Malta

Background Obesity is a global epidemic with the Mediterranean island of Malta being no exception. The World Health Organization (WHO) has identified Malta as one of the European countries with the highest obesity prevalence. Method A cross-sectional study was conducted (2014-2016) under the auspices of the University of Malta. The prevalence of overweight-obesity in Malta was calculated and then age stratified for comparisons with previous studies. Results The study identified 69.75% (95% CI: 68.32-71.18) of the Maltese population to be either overweight or obese. The men overweight/obese prevalence (76.28% 95% CI: 74.41-78.14) was statistically higher than that for women (63.06% 95% CI: 60.92-65.20) (p=0.0001). Age stratification revealed that both genders had the highest overweight prevalence rates between 55 and 64years (Men=23.25% 95% CI: 20.43-26.33; Women=24.68% 95% CI: 21.44-28.22). Men obesity prevalence rates were highest in the 35 to 44years group (22.52% 95% CI: 19.65-25.68) while for women it was highest in the 55 to 64years group (28.90%, 95% CI: 25.44-30.63). Conclusion Over a 35-year period, an overall decrease in the normal and overweight BMI categories occurred with an increase in the prevalence of obesity. An exception was observed in the women, where the prevalence of normal BMI increased over this time period. Also, it appears that while the total population obesity prevalence increased (for 2016), a percentage of the women have shifted from an obese to an overweight status.
