Reduction in blood pressure , lipids and blood glucose was not statistically significant .
Conclusions Workplace interventions  significantly reduced body weight , BMI and waist circumference .
Non-significant results for biochemical markers could be due to them being secondary outcomes in most studies .
Background Adults in urban areas spend almost 77 % of their waking time being inactive at workplaces , which leaves little time for physical activity .
The aim of this systematic review and meta- analysis was to synthesize evidence for the effect of workplace physical activity interventions on the cardio-metabolic health markers ( body weight , waist circumference , body mass index ( BMI ) , blood pressure , lipids and blood glucose ) among working adults .
Effectiveness of a Group Support Lifestyle Modification (GSLiM) Programme among Obese Adults in Workplace: A Randomised Controlled Trial
Background There was an increasing trend in the prevalence of obesity and its comorbidities over the past decades in Malaysia . Effective intervention for obesity remains limited . This study aim ed to compare the effectiveness of a group based lifestyle modification programme  amongst obese individuals with an existing dietary counseling programme . Methods We recruited one hundred and ninety four overweight and obese ( BMI > 27.5 kg/m2 ) employees from a local university . They were r and omly allocated to either Group Support Lifestyle Modification ( GSLiM ) (intervention)(n = 97 ) or dietary counseling (comparison)(n = 97 ) . The GSLIM activities included self monitoring , cognitive-behaviour sessions , exercise as well as dietary change advocacy , which were conducted through seminars and group sessions over 24 weeks . The comparison group was given dietary counselling once in 12 weeks . Both groups were followed up for additional 12 weeks to check for intervention effect sustenance . Anthropometric and biochemical parameters were measured at baseline , 12 , 24 and 36 weeks ; while dietary intake , physical activities , psychological measures and quality of life measured at baseline , 24 and 36 weeks . Data analysis was conducted using ANOVA repeated measures with intention to treat principle . Results The participants were predominantly women with mean ( st and ard deviation ) age of 40.5 ( 9.3 ) years . A total of 19.6 % of the participants in GSLiM achieved 6 % weight loss compared to 4.1 % in the comparison group ( Risk Ratio 4.75 ; 95 % CI : 1.68 , 13.45 ) . At 24 weeks , the retention rate was 83.5 % for GSLiM and 82.5 % for comparison group . GSLiM participants also achieved significant improvement in total weight self-efficacy score , negative emotions and physical discomfort subscales , MDPSS friend subscale and all domains in quality of life . Participants in the comparison group experienced reduction in negative self-thoughts . Conclusion The GSLiM programme proved to be more effective in achieving targeted weight loss , improving weight self-efficacy , friend social support , and quality of life compared to dietary counseling .
