Health habits during lockdown for COVID-19 in Spain and its effect on weight

Background and objectives: a deterioration of health habits has been found in various studies caused by stressful situations such as mandatory and maintained confinement over time. This study aims to analyze the health habits of the Spanish adult population during confinement due to the COVID-19 pandemic, and the possible impact on their body weight. Method: two thousand eight hundred and thirty-four volunteer subjects participated in the study (69.3 % women). They completed an on-line questionnaire that evaluated their health habits, as well as various sociodemographic variables. Results: the results show a statistically significant link between the subjects' body mass index (BMI) and the change in their weight during lockdown (2: 79.303; p: < 0.001). Besides, a statisti-cally significant relationship between the different health habits under analysis was also found, being moderate with respect to the link between eating habits and physical activity (Cramer's V: .226). A statistically significant relationship was also found between the participants' weight and the different health habits during lockdown. The effect size of the associations was moderate in relation to the participants' eating habits (Cramer's V: .409) and physical activity (Cramer's V: .292). Conclusions: it is suggested the development of prevention programs for long lockdown periods associated with high levels of stress so as to promote a healthy diet, as well as exercise using new technologies and a proper rest, especially in overweight or obese subjects.
