For SHG, professionals guide diet and physical activity to achieve body weight (BW) waist circumference (WC) reductions.

Methods: Our was performed smartphone application videophone message exchanges provided by professionals. We analysed 1,994 participants. Primary outcomes included changes after versus before used multiple linear regression analyses identify due Results: The mean ages were 49.3 (standard deviation [SD], 5.8) years males 50.5 (SD, females. change -1.37 kg both sexes. -1.05 -2.05 cm males, baseline mass index, pre-intervention action history, numbers communications messages significantly larger WC. females, no significant reduction, while history reduction. Conclusions: reduces Videophone messaging are males. These results may help improve efficacy SHG.
