PREVALENCE OF OBESITY AND THE RELATIONSHIP BETWEEN BODY MASS INDEX AND HEALTH RELATED QUALITY OF LIFE AMONG ADULTS IN MUSHIN LOCAL GOVERNMENT, LAGOS STATE, NIGERIA
Introduction: Body fat distribution is a significant determinant of health and disease; both obesity and underweight have been associated with several non-communicable diseases. There is a paucity of research regarding the role played by anthropometrics on the Quality Of Life among adults as reported by individuals themselves in the country and other countries in sub-Saharan Africa. The purpose of this study was to determine the prevalence of obesity and the relationship between anthropometrics and associated factors, and Health Related Quality of Life among adults in Mushin Local Government Area of Lagos state, Nigeria.
Materials and methods: This was a cross-sectional descriptive study. A multistage sampling technique was used to select 400 households in which one individual 15 years and above per household was selected. A pre-tested interviewer administered structured questionnaire with a visual analogue scale was administered to the selected people. The individuals’ weight, height, waist circumference and blood pressure were also measured. The questionnaire contains information on individual’s biodata, life style and the short version of the WHO Quality of life assessment.
Results: The age range was 15 to 80 years, while the mean age was 36.7 ± 13.7 years. The majority (70.3%) were females. The prevalence of overweight and obesity using BMI were 30.3% and 14.2% respectively. The prevalence of obesity using waist circumference among male and female respondents were 7.3% and 30.1% respectively. The prevalence of raised blood pressure among the respondents was 25.2%. This study found the overall quality of life to be fair with only 8.0 % and 22.7% having good and poor value respectively. Also, satisfaction with health was fair among
the majority (69.0%), with 57 (14.2%) and 67 (16.8%) having good and poor values respectively. The quality of life was fair in all the domains in the majority with mean values ranging from 60.4 in environment domain to 72.7 in physical domain. There were weak negative correlations between global domain of quality of life and age (r = -0.35), family size (r = -0.30), Body Mass Index (r = -0.10), waist circumference (r = -0.20), systolic blood pressure (r = -0.27) and diastolic blood pressure (r = -0.22), but there were weak positive correlations between global domain of health related quality of life and personal monthly income (r = 0.28), family monthly income (r= 0.28) and household monthly expenditure of feeding (r = 0.14). The factors found to significantly influence the Health Related Quality Of Life were age, income, Body Mass Index and blood pressure.
Conclusion: This study has shown that socio-economic as well as anthropometrics and related factors significantly influence the health related quality of life of the adults in Mushin Local Government Area of Lagos State
Recommendations: The local governments should ensure community mobilization and education on the importance of maintaining appropriate body weight and mobilize individuals to adopt nutritional practices and other life style modifications that will promote their health.
