This study primarily investigated whether a primarily telehealth lifestyle intervention reduced excess GWG among women with overweight or obesity.Usual antenatal care included an antenatal visit at 7–10 weeks’ gestation, an additional seven antenatal visits, on average, and periodic health education newsletters, including the IOM GWG guidelines and information on healthy eating and physical activity in pregnancy. 

Ladies at 8–15 weeks’ incubation with singletons, pre-pregnancy BMI 25·0–40·0 kg/m 2, and matured 18 years or more seasoned were haphazardly appointed (1:1) to get the telehealth way of life mediation or normal antenatal consideration. Randomisation was adaptively adjusted for age, BMI, and race and identity. Examinations remembered 199 ladies for the way of life mediation gathering (one lost to development) and 195 in the standard consideration gathering (three lost to development). 96 (48%) ladies in the way of life intercession gathering and 134 (69%) ladies in the standard consideration bunch surpassed Institute of Medicine rules for pace of GWG every week (relative danger 0·70, 95% CI 0·59 to 0·83). Contrasted and common consideration, ladies in the way of life intercession had diminished week by week pace of GWG (mean 0·26 kg every week [SD 0·15] versus 0·32 kg every week [0·13]; mean between-bunch distinction −0·07 kg every week, 95% CI −0·09 to −0·04).

To conclude , we can say that the this evidence-based programme showed that health-care delivery systems could further adapt to meet the needs of their clinical settings to prevent excess GWG and improve healthy behaviours and markers of insulin resistance among women with overweight or obesity by using telehealth lifestyle interventions.
