Effectiveness of video assisted aerobic dance therapy on reduction of body mass index among obese women residing in selected villages at Tirunelveli district.

An experimental study to assess the effectiveness of video assisted aerobic dance therapy on reduction of Body Mass Index(BMI) among obese woman residingin selected villages atTirunelveli District was conducted by Mrs. G. Saraswathi in partial fulfillment of the requirement for the degree of Master of Science in Nursing at Sri. K.Ramachandran Naidu College of Nursing,under the TamilnaduDr.M.G.R. Medical University,Chennai in 2012. Obesity is an abnormal increase in the proportion of fat cells. Obesity is the second leading cause of preventable death. Lack of physical exercise is another factor that contributes to weight gain and obesity. There is a reduction in physical activity, both in the workplace and at home. Obesity is a serious medical condition this needs urgent attention throughout the world.Obesity is harder to treat in adults than in children. This can be achievedby dietary changes, increased physical activity and a combination of both.Increased physical activity is an important part of weight reducing program. Regular physical exercise is the key to increased energy expenditure. Dance aerobics is an exercise that combines the rhythmic steps of aerobics with graceful dance movements. During muscular exercise, when large amounts of lactic acid escape as a result of glycolysis. The glycogen stored in the muscle and it will beconverted in to glucose by the process of glycolysis. Objectives of the study were: To assess the pretest level of BMI among obese women of experimental and control group. To find out the effectiveness of Aerobic Dance Therapy on reduction of BMI among obese women in experimental group and control group. To compare the pre-test and post-test level of BMI among obese women in the experimental group. To associate the post test level of BMI among obese women in experimental group with their selected demographic variables. To associate the post test level of BMI among obese women in control group with their selected demographic variables. Hypothesesof the study were: All hypotheses were tested at 0.05 levels. H1 Meanpost test level of BMI among obesewomenin experimental group was significantly lower than the mean post test level of BMI among obese women in control group. H2 There was a significant difference between pre test and post test level of BMI among obese women in experimental group. H3 There was a significant association in the post test level of BMI among obese women of experimental group with the selected demographic variables. H4 There was a significant association in the post test level of BMI among obese women of control group with the selected demographic variables. The study was based on Modified Dorothai Johnson behaviormodel. A true experimentalpre test, post testcontrol group design was used in this study .This study was conducted in selected villages at Tirunelvelli district. Sixty obese women were categorized into mild, moderate andsevere based on BMI scoring and they were randomly assignedinto experimental group (N=30) and control group (N=30). The samples of experimental group were belongs to Thiruvannathapuram village.The samples of control group were belongs to Natham village. The data were collected from 02.04.2011 to 30.04.2011.The experimental group had undergone physical activity (Aerobic Dance Therapy) for the period of 20 consecutive days where as the control group did not. BMI scale was used to categories obese women based on body weightduring pre test. Interview method was used to find the demographic data .The data were analyzed using descriptive and inferential statistics. The significant findings of the study were: The post test level of BMI among obese women in experimental group was significantly lower than the mean post test level of BMI among obese women in control group. (t = 1.82, p< 0.05). The mean post test level of BMI among obese women in experimental group was significantly lower than the mean pre test level of BMI. (t = 12.04, p < 0.05). There was no significant association between the post test level of BMI among obese women in the experimental group and control group with their selected demographic variables except age
