Relationship between physical activity, body mass index (BMI) and lipid profile of students in Ghana

Abstract

Introduction: in Ghana, there is no data regarding physical activity habits and lipid profiles of students. Therefore, the aim of this study was to
investigate the relationship between physical activities, Body Mass Index (BMI) and lipid profile of students in Ghana. Methods: cluster and
systematic sampling techniques were employed to recruit 120 students, aged 18 years and above. This cross-sectional study was carried out among
students from the University of Ghana. Biochemical analysis was conducted analysing total cholesterol (TC), high density lipoprotein (HDL), low
density lipoprotein (LDL) and triglycerides (TG) in serum samples. Anthropometry measurements were also taken and BMI calculated. The physical
activities, undertaken over a 7-day period, by the students were assessed using the International Physical Activity Questionnaire (IPAQ).
Results: 31.7% and 21.7% of the students were overweight and obese respectively. 61.5% of the obese students were engaged in high level
physical activity as compared to 45.5% and 36.8% of the normal and overweight students, respectively. Normal weight students and overweight
students showed significant differences in means of TC; [(4.56 ± 0.930 mmol/L) and (5.06 ± 0.93 mmol/L), respectively] and also between normal
weight group (4.54 ± 0.93 mmol/L) and the obese students (5.24 ± 1.18 mmol/L). Significant correlations were also observed between TG, TC and
BMI; and TC and TG, HDL and a strong correlation between LDL and TC (r=0.967). Conclusion: strong correlations between BMI, physical activity
and lipid profile indices among students in Ghana. Comprehensive efforts should be applied to reduce the incidence of CVDs among students.
