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 6 Months of Tailored Text Message Reminders for Obese Male Participants in a Worksite Weight Loss Program: Randomized Controlled Trial
Background Worksite nutrition and physical activity interventions are important to help overweight and obese employees lose weight , but costs and insufficient sustained motivation prevent the majority of these programs from succeeding . Tailored text messaging in aiding weight management has been effective in several studies , but no studies have evaluated the effect of a tailored text message service on weight loss in a worksite health promotion program . Objective We studied the efficacy of a tailored text-messaging intervention for obese male participants in a worksite weight loss program of 6 months duration . Methods The study was an unblinded , r and omized controlled trial . Men with a body mass index greater than 25 kg/m2 were recruited from the Korea District Heating Corporation , the Korea Expressway Corporation , and the Korea Gas Corporation . The participants were identified by nurse managers . Participants were r and omly allocated to 1 of the following 2 groups for 24 weeks : ( 1 ) intervention group , which received tailored text message reminders every other day plus 4 offline education sessions and brief counseling with monthly weight check by nurses for weight control over 6 months and ( 2 ) control group , which received the 4 offline education sessions and brief counseling with monthly weight check by nurses about weight control over 6 months . The primary outcome was the difference in weight loss at 6 months . A mixed-model repeated- measures analysis was performed to evaluate the effect of the intervention group ’s weight loss compared with the control group . Results A total of 205 obese men were r and omized into either the intervention ( n=104 ) or the control group ( n=101 ) . At the end of 6 months , the intervention group ( n=63 ) had lost 1.71 kg ( 95 % CI –2.53 to –0.88 ) and the control group ( n=59 ) had lost 1.56 kg ( 95 % CI –2.45 to –0.66 ) ; the difference between the 2 groups was not significant ( mean difference –0.15 , 95 % CI –1.36 to 1.07 ) . At the end of the study , 60 % ( 34/57 ) of the intervention group rated the message program as helpful for weight control and 46 % ( 26/57 ) would recommend the text message service to their friends . Conclusions Tailored text message reminders did not have a significant effect on weight loss in obese men as part of a worksite weight loss program .
