“…In the present study, lower baseline PA during transport was consistent with those of other studies (29)(30)(31). It is recommended that programing to promote and support walking and cycling as daily trips can significantly provide the situation for regular PA (32).…”

Background: Sedentary behavior, time spent sitting, is particularly worrisome because several studies indicated the health threatening outcomes of long time sitting, while few interventions aimed at reducing the sitting time. Objectives: The current study aimed at reducing the sitting time and promoting physical activity (PA) among females with sedentary behaviors through providing social support. Methods: The study was a randomized, controlled trial conducted from September to December 2014 in Jolfa, East-Azerbaijan, Iran. The study was designed to assess the effect of social support on the reduction of sitting time. A total of 230 female teachers (115 per arm) from 16 primary and secondary schools were invited to participate in the current study. The outcomes were the changing the sitting time pattern and increased PA. A self-reported questionnaire consist of 3 parts was used at baseline and 8 weeks after the intervention. Results: The mean age (standard deviation (SD) of the participants were 42 (5.4) years. Participants in both intervention and control groups reported a significant increase in their PA at work that was in favor of the intervention group (at baseline: 112 versus 153 metabolic equivalent of task (MET)-minute/week; after intervention: 399 versus 154 MET-minute/week) (P < 0.05). Considerable differences between the intervention and control groups were observed in terms of siting time (at baseline: 25.8 versus 25 hour/ week; after intervention: 19.3 versus 24.3 hour/week). The reduction was significantly higher in the intervention group (6 hour/week) than the control group (0.8 hour/week). Conclusions: The findings indicated that providing a social support in schools for female teachers may improve several domains of PA and aggravate mental and physical workplace-related problems.

“…Physical activity or inactivity did not contribute to pattern 2. However, in a previous analysis of physical activity in this population ( 16 ) , the mean physical activity has been found to be higher than the recommended energy expenditure on physical activity for health benefits based on global guidelines across the population, which may possibly explain why physical activity did not emerge as a component of pattern 2 or 1.…”

“…The only study in this direction has been that of clustering of energy-related behaviour in children through PCA ( 15 ) . Our previous analysis of physical activity in urban women has shown that dysglycaemia is prevalent despite high levels of physical activity and low sedentary behaviour, necessitating further study of lifestyle in its entirety ( 16 ) . PCA has traditionally been used for analysing variables obtained through frequency questionnaires, but conceptually quantification such as the use of food portion sizes and metabolic equivalents for physical activity would allow a better representation of actual real-life patterns.…”

Lifestyle patterns and dysglycaemic risk in urban Sri Lankan women

Specific dietary patterns are associated with the risk of chronic disease. An in-depth understanding more reflective of lifestyle would be possible when assessing the synergistic effects of both diet and physical activity in pattern analysis. In the present study, we examined the biochemical markers of dysglycaemia and cardiometabolic risk in relation to lifestyle patterns using principal component analysis (PCA). Urban women (n 2800) aged 30 -45 years were screened for dysglycaemia using cluster sampling from the Colombo Municipal Council area. All the 272 dysglycaemic women detected through screening and 345 randomly selected normoglycaemic women were enrolled. The International Physical Activity Questionnaire and a quantitative FFQ were used to assess physical activity and diet, respectively. Anthropometric measurements, bioelectrical impedance analysis and biochemical estimations were carried out. Lifestyle patterns were identified based on dietary and physical activity data using exploratory factor analysis. PCA was used for the extraction of factors. A total of three lifestyle patterns were identified. Women who were predominantly physically inactive and consumed snacks and dairy products had the greatest cardiometabolic risk, with a higher likelihood of having unfavourable obesity indices (increased waist circumference, fat mass percentage and BMI and decreased fat-free mass percentage), glycaemic indices (increased glycosylated Hb (HbA1c) and fasting blood sugar concentrations) and lipid profile (increased total cholesterol/TAG and decreased HDL-cholesterol concentrations) and increased high-sensitivity C-reactive protein concentrations. For the first time, we report lifestyle patterns and demonstrate the synergistic effects of physical activity/inactivity and diet and their relative association with cardiometabolic risk in urban women. Lifestyle pattern analysis greatly increases our understanding of high-risk behaviours occurring within real-life complexities.

“…The concept of ethnicity specific recommendation for physical activity has been discussed elsewhere. A recent study in Sri Lankan women demonstrated women who self-reported less than 2,640 MET-minutes.week -1 of moderate to vigorous physical activity (~400–800 minutes per week of moderate intensity physical activity) are more likely to exhibit impaired glycaemia compared to women with self-reported weekly activity greater than this threshold (sensitivity 84% and specificity 85%) [ 36 ]. Although that study supports the concept of greater physical activity requirements for South Asian women, it is important to recognize that the use of self-reported questionnaires substantially overestimates physical activity [ 37 ] and limits the analysis exploring the actual dose-response relationship between physical activity and glycaemia.…”

Should Physical Activity Recommendations for South Asian Adults Be Ethnicity-Specific? Evidence from a Cross-Sectional Study of South Asian and White European Men and Women

et al. 2016

International public health guidelines recommend that adults undertake at least 150 min.week−1 of moderate-intensity physical activity. However, the underpinning evidence has largely been obtained from studies of populations of white European descent. It is unclear whether these recommendations are appropriate for other ethnic groups, particularly South Asians, who have greater cardio-metabolic risk than white Europeans. The objective of our study was to determine the level of moderate-intensity physical activity required in South Asians adults to confer a similar cardio-metabolic risk profile to that observed in Europeans of similar age and body mass index (BMI) undertaking the currently recommended levels of 150 min.week−1. 148 South Asians and 163 white Europeans aged 18 to 70 years were recruited. Physical activity was measured objectively via vertical axis accelerations from hip-worn accelerometers. Factor analysis was used to summarize the measured risk biomarkers into a single underlying latent “factor” describing overall cardio-metabolic risk. Sex did not modify the association between physical activity and the cardio-metabolic risk factor, so data for both sexes were combined and models adjusted for age, sex, BMI and accelerometer wear time. We estimated that South Asian adults needed to undertake 232 (95% Confidence interval: 200 to 268) min.week−1 in order to obtain the same cardio-metabolic risk factor score as a white European undertaking 150 minutes of moderate-equivalent physical activity per week. The present findings suggest that South Asian men and women need to undertake ~230 minutes of moderate intensity physical activity per week. This equates to South Asians undertaking an extra 10–15 minutes of moderate intensity physical activity per day on top of existing recommendations.
