Effect of physical activity on fasting blood glucose and lipid profile among low income housewives in the MyBFF@home study

Abstract

BackgroundRegular physical activity has always been strongly recommended for good cardiovascular health. This study aimed to determine the effect of physical activity on fasting blood glucose and lipid profile among low income housewives in Klang Valley.MethodsData of 328 eligible housewives who participated in the MyBFF@Home study was used. Intervention group of 169 subjects were provided with an intervention package which includes physical activity (brisk walking, dumbbell exercise, physical activity diary, group exercise) and 159 subjects in control group received various health seminars. Physical activity level was assessed using short-International Physical Activity Questionnaire. The physical activity level was then re-categorized into 4 categories (active intervention, inactive intervention, active control and inactive control). Physical activity, blood glucose and lipid profile were measured at baseline, 3rd month and 6th month of the study. General Linear Model was used to determine the effect of physical activity on glucose and lipid profile.ResultsAt the 6th month, there were 99 subjects in the intervention and 79 control group who had complete data for physical activity. There was no difference on the effect of physical activity on the glucose level and lipid profile except for the Triglycerides level. Both intervention and control groups showed reduction of physical activity level over time.ConclusionThe effect of physical activity on blood glucose and lipid profile could not be demonstrated possibly due to physical activity in both intervention and control groups showed decreasing trend over time.

Association of physical activity, sedentary behaviours and sleep duration with cardiovascular diseases and lipid profiles: a Mendelian randomization analysis

“…But this MR study confirmed the findings from a Japanese prospective study showing that excessive vigorous-intensity activities might not be beneficial or even disadvantageous for prevention of hemorrhagic stroke for Japanese people [42]. Likewise, there was few significant effect of physical activity on lipid profiles among groups in intervention studies, which was consistent with our null finding [43,44]. Further investigations are warranted to elucidate the potential association between physical activity and different stroke subtypes or lipids.…”

The associations between health-related physical fitness and fasting blood glucose in war veterans: a population-based study

“…It has been reported, that three-quarter of cardiovascular deaths can be prevented by embracing healthy lifestyle changes 13 , including adequate physical activity. Evidence suggests that regular physical activity may have beneficial effects on blood glucose control 1 , 13 – 17 and glycemic variability 18 .…”

Association of PC Use and TV Viewing Hours with Women’s Recreational Physical Activity and Its Impact on Their Obesity Indices

“…Sedentary behavior may be a critical determinant of health, independent of physical activity [10,11]. Sedentary lifestyle and physical inactivity are common practices worldwide and are associated with a wide range of chronic diseases and premature death [12,13]. Although inactivity is known to be harmful, almost one-third of the world's population remains inactive, posing a great risk for public health [14].…”
