Abstract
A Quasi- experimental study (before-and- after with control group design) was conducted to assess the effectiveness of Interventions to reduce weight among women with obesity using Quantitative Evaluative approach. The study setting adopted was two stage random sampling technique with lottery method. Using Non probability purposive sampling technique, Each 100 women with obesity aged 20- 39 years were selected for experiment and control group. Established Reliability and Pilot study.
In pretest, both groups’ baseline data obtained through Structured Interview Schedule, obesity parameters (BMI, WC) assessed to identify the level and health risk status. Implementation of Interventional Module on Interventions to reduce weight was administered to experiment group subjects for 12 weeks. Posttest conducted for both groups. The collected data were analyzed using descriptive and inferential statistics.
The findings revealed highest percentages of women with obesity in control and experiment group were aged 35-39 years with primary/middle school education. Mostly Hindus, married, non-vegetarian, sedentary workers, nuclear family, monthly income Rs.10,001–15,000, having regular menstrual cycle and children, fat distributed above waist line, sleep pattern >6 hours/day, no family history of obesity and social habits.
The comparison and distribution of mean posttest values of BMI (32.56 ± 3.46 and 28.44 ± 2.89), WC (40.75 ± 4.25 and 36.11 ± 3.96) among women with obesity between control and experiment group shows high mean difference of 4.12, 4.64 respectively. The unpaired ‘t’ test values of BMI (9.12), WC (5.28) found to be > the table value (3.291) at p<0.001.
The paired ‘t’ test analyzed the significant difference in mean pre and posttest values of BMI (32.09 ± 3.26 and 28.44 ± 2.89), WC (40.44 ± 4.25 and 36.11 ± 3.96) among women with obesity in experiment group shows high mean difference 3.65, 4.33. The ‘t’ values of BMI (40.78), WC (31.05) found to be > the table value (3.291) at p<0.001. The mean posttest values of BMI and WC showed significant difference in experimental group.
Chi square analysis between posttest values of BMI, WC found associated only with the duration of sleep at night (p<0.05) and social habits (p<0.001) with BMI, age in years and educational status (p<0.001) with WC. The implementation of Interventional Module on Interventions to reduce weight found to be effective in reducing weight among the subjects in experimental group.
