Abstract
OBJECTIVES: To determine the prevalence of obesity in adolescent girls attending gynaecology out-patient clinic. To assess the menstrual pattern in obese adolescent girls and to determine the proportion of obese girls with irregular cycles who have PCOD. To assess the risk factors associated with obesity. METHOD: Sample size was calculated to be 162. The inclusion criteria was adolescent girls (aged 12-19 years) attending the gynaecology out-patient clinic of Christian Medical College, Vellore from January 5, 2017 to June 7, 2017 and consenting to be a part of the study. The exclusion criteria was adolescent girls who were medical, nursing or allied health students of CMC and girls not consenting for the study. Methodology – Patient was recruited after taking informed consent of patient and guardian. A questionnaire was filled based on one on one interview. Following this a physical examination was carried out. All adolescents with history of menstrual irregularities suggestive of oligo-ovulation/ anovulation were advised to undergo ultrasonography to evaluate for the presence of polycystic ovaries. Data analysis was done using SPSS 16.0. Mean and standard deviation was used to describe continuous variables while frequency and percentages obtained for categorical data. The chi square and the student t test was employed to study the statistical significance of categorical and continuous variables respectively. RESULT: 501 girls were recruited for the study. The prevalence of obesity and overweight was 14% and 18% respectively. 70 girls were found to be obese and 70% of them had irregular cycles. 45% of the obese girls with irregular cycles had PCOM. Statistically significant corelation was found between obesity and the following:- weight at birth, fathers BMI, mothers BMI, obesity in sibling, physical activity, regular exercise and acanthosis nigricans. CONCLUSION: 1. The prevalence of obesity in the adolescent age group was 14% and the prevalence of overweight was 18%. 2. 70% of the obese girls had irregular cycles. 3. 45% of the obese girls with irregular cycles had PCOM. 4. Risk factors which were significantly associated with adolescent obesity were – birth weight, fathers BMI, mothers BMI and obesity in sibling. 5. Physical activity and regular exercise were significantly associated with less obesity in the adolescent period. 6. Risk factors which were not associated with adolescent obesity were- breast feeding practices, SES, skipping of breakfast, eating out, intake of soft drinks, daily intake of fruits and vegetables, screen time and time spent in desk bound activities. 7. Acanthosis nigricans was seen significantly more in obese adolescents than in adolescents with normal BMI. 8. Adolescents with normal BMI can have a waist hip ratio more than 0.8.
