A rapid study conducted by Farouk Boudou and colleagues shows that the Covid-19 lockdown led to significant weight gain among Algerians.
The objective of the study was to assess the potential influence of lifestyle changes during the first month of COVID-19 lockdown on body weight gains (WG) in an Algerian population cohort. A sample survey using self-administered questionnaire was used to solicit data from 172 randomly selected participant over social networks. The recorded anthropometric (body) measurements in relation to lifestyle factors include physical activity, diet habits, sleep, and screen time.
The study result reveals an over-all weight gain for men and women within the sampled population as shown in Δ-BMI (body mass index differenc e before and after one month of lockdown period) for the total sample, men and women respectively.
Significantly, a positive correlation exists between body WG and amount of meals/day in men (r=0,341, p=0,012), while for women there was a positive correlation between WG change and both food intake (r=0.170, p=0.066) and nighttime snacking (r=0,228, p=0,013). Furthermore, a negative correlation between WG and sport practicing was found in women (r =-0.221, p=0.016).
The research therefore concluded that significant WG was found during a short Covid-19 lockdown. The WG results presented herein were positively associated with certain lifestyle variables during the Covid-19 lockdown.
