Back ground: The incidence of obesity in middle age as already rose to an alarming number and many variables have been associated with the decline of level of physical activity in obese middle aged adults. However very little is been studied about the impact of falls/stumbles in decreasing the level of physical activity. Objective: The purpose of this study is (1) to examine the relationship between incidences of fall/stumbles and physical activity level in obese middle aged adults (2) to explore potential explanatory factors and preserve the level of Physical activity. Hypothesis: Incidence of falls might significantly influence the level of physical activity in obese middle aged subjects. Study design: Cross sectional, Observation study Outcome measures: Long form of International physical activity questionnaire (IPAQ) a)Categorical variable b) Continuous score-MET-min/day/week. Participants: In total 326 obese __ampersandsignnbsp;middle aged subjects of both genders between age 40-60 years (Mean age: 52.3) with BMI ?30 kg/m2 were enrolled in this study. Intervention: Not applicable Methods: Subjects were retrospectively questioned and categorized as Group A (obese fallers), N=73 and Group B (obese non fallers), N=253 using fall history questionnaire. All subjects were evaluated with base line assessment, International physical activity questionnaire (IPAQ- long term design) continuous score (MET-minutes)and categorical scoring pattern was used in IPAQ for data collection after obtaining consent. Results: Group A mean MET __ampersandsignndash;min/day/week was 472.75 (S.D-288.384), Group B mean MET-min/day/week was 739.81(S.D- 341.165) in continuous score comparison .Mann- Whitney U test analysis revealed that there was a significant difference in the level of physical activity between the groups. Chi-square analysis of categorical data between groups states that the significant difference between expected and observed frequencies is not by chance alone. Conclusion: Incidence of falls/stumble is associated with decline in physical activity levels of major domains among middle aged obese subjects.
