Worldwide, COVID-19 pandemic and lockdown might increase anxiety and depressive symptoms. The authors conducted an online survey of the general Spanish adult population two weeks after an official lockdown was established across the country as a quarantine. Results showed that: - sixty-five percent of the participants (mean age = 47 years; 73% females) reported anxiety or depressive symptoms (anxiety: 39% mild, 11% moderate, 4% severe; depressive: 29% mild, 9% moderate, 6% severe). - following a balanced diet and not reading news/updates about COVID-19 very often were the best predictors of lower levels of anxiety symptoms. - following a balanced diet, following a routine, not reading news/updates about COVID-19 very often, taking the opportunity to pursue hobbies, and staying outdoors or looking outside were the best predictors of lower levels of depressive symptoms. Authors conclude that simple coping behaviours may protect against anxiety and depressive symptoms during the COVID-19 pandemic and lockdown.
Abstract
BACKGROUND The COVID-19 pandemic and lockdown might increase anxiety and depressive symptoms, but some behaviors may protect against them. METHOD To provide a preliminary evidence of the behaviors associated with decreased symptoms in the current COVID-19 pandemic and lockdown, we conducted a survey of 5545 adult individuals from the Spanish general population, two weeks after an official lockdown was established across the country. RESULTS Sixty-five percent of the sample reported anxiety or depressive symptoms. Following a healthy/balanced diet and not reading news/updates about COVID-19 very often were the best predictors of lower levels of anxiety symptoms. Following a healthy/balanced diet, following a routine, not reading news/updates about COVID-19 very often, taking the opportunity to pursue hobbies, and staying outdoors or looking outside were the best predictors of lower levels of depressive symptoms. LIMITATIONS Cross-sectional nature and use of sample of convenience. CONCLUSIONS This study suggests that "simple" coping behaviors may protect against anxiety and depressive symptoms during the COVID-19 pandemic and lockdown.

Plain language summary
Obesity in children and adults is increasingly becoming a serious health problem, particularly in Western countries. The precise biological mechanisms underlying the disease are not clear, and it is equally unclear why certain individuals are more predisposed than others. Research suggests that the perinatal conditions and periods of organ development may predispose individuals to obesity later in life. For example, maternal malnutrition, diabetes and/or obesity during pregnancy can increase susceptibility to obesity. The hypothalamus, the region of the brain associated with feeding and glucose homeostasis, develops primarily in utero and is thought to be influenced by hormones such as leptin, ghrelin and insulin that may indicate nutrient availability in the environment. Imbalances in these hormones therefore may have an impact on the developing hypothalamus, leading to abnormalities in appetite control and feeding. These hormones may also be involved in neural growth and development directly.
Abstract
Obesity in adults and children is increasingly becoming a major health problem worldwide. However, the precise biological mechanisms governing this disease have not been fully elucidated. Obesity involves the complex interaction of a wide range of environmental and genetic factors. Additionally, there is now a growing body of evidence suggesting that alterations in metabolic environment during important periods of organ development can predispose individuals to later development of obesity and diabetes. Maternal obesity or malnutrition during pregnancy increases the risk for metabolic disorders (including obesity) in the offspring. Similarly, early postnatal overnutrition also predisposes offspring to adult obesity. The hypothalamus appears to play an essential role in controlling appetite. It undergoes a tremendous growth beginning early in gestation and continuing during the postnatal period. These developmental windows represent periods of sensitivity for hypothalamic development during which alterations in the nutritional and/or hormonal environment may perturb hypothalamic development and subsequent function.
