Body image dissatisfaction, nutritional status and weight control strategies among university undergraduates in Lagos: a descriptive cross-sectional study

Abstract

Introduction: body image dissatisfaction has been associated with poor nutritional status and unhealthy weight management strategies. This study determined the prevalence and relationships between body image dissatisfaction, nutritional status, and weight management strategies among university undergraduate students in Lagos, Nigeria.

Methods: a descriptive cross-sectional study employed a multi-stage sampling technique to select 865 undergraduates in Lagos. A pretested self-administered questionnaire was used to assess the variables. Stunkard figure rating scale was used to determine body image dissatisfaction. Body mass index (BMI) was calculated to determine nutritional status. A standard weight control strategy scale was adopted to determine weight management strategies. SPSS (version 23) was used for analysis and the association between variables was determined using Chi-square. The level of significance was set at P= <0.05.

Results: the prevalence of body image dissatisfaction was high (63.5%) but not associated with gender. The majority (65.1%) had normal BMI, 10.6% were overweight and 7.2% were obese. Majority of the respondents (93.3%) engaged in weight management practices with dietary control being the most employed strategy. The most commonly employed unhealthy practice is strict dieting (37.7%). Body image dissatisfaction was significantly associated with overweight/obesity (P=0.001) but not with weight management practices. Age and overweight/obesity were predictors of BID.

Conclusion: prevalence of body image dissatisfaction, overweight and obesity, and unhealthy weight management strategies were high. Body image dissatisfaction was associated with obesity but not associated with weight management strategies. All undergraduates need health education on body image and appropriate weight management strategies.
