A partir de dados coletados por amostragem em bola de neve, por meio de um questionário online foi realizado um estudo caso-controle. Durante o período de novembro de 2020 a abril de 2021, 6.360 pessoas com idade média de 43,5 anos (DP = 14,3) participaram da pesquisa. No presente estudo, foram considerados 158 casos de transtorno de insônia e 476 controles (três controles por caso) selecionados aleatoriamente dentre os participantes sem problemas de sono. Os resultados da análise comparativa entre casos e controles mostraram que dormir menos de seis horas diárias (OR = 3,89; IC95% 2,50-6,05), sentir tristeza frequentemente (OR = 2,95; IC95% 1,69-5,17), residir em metrópoles (OR = 1,71; IC95% 1,04-2,84), estar com 40 anos ou mais (OR = 1,93; IC95% 1,22-3,06) e a interação entre ocupação e escolaridade mais precária (OR = 2,12; IC95% 1,22-3,69) foram fatores preditores para sintomas de transtorno de insônia durante a pandemia. Além da confirmação da hipótese de que problemas de saúde mental estão associados a sintomas de insônia, os resultados apontam para a insônia como um desfecho importante para estudos sobre efeitos do desemprego, vulnerabilidade e baixa escolaridade da população, sobretudo nas grandes metrópoles, ressaltando que os efeitos da crise sobre a saúde e a economia são distribuídos de forma extremamente desiguais.

METHODS A survey was distributed using social media and organizational emails to Brazilian active health care professionals during the COVID-19 outbreak. We explored potential associated factors including age, gender, occupation, workplace, work hours, income, previous infection with COVID-19, recent/current contact with COVID-19 patients, regional number of incident deaths, anxiety, and burnout. We evaluated new-onset/ previous insomnia worsening episodes (primary outcome), new pharmacological treatments, sleep quality, duration, nightmares and snoring (secondary outcomes). RESULTS A total of 4,384 health professionals from all regions of the country were included in the analysis (44±12 years, 76% females, 53.8% physicians). Overall, 55.7% were assisting patients with COVID-19, and 9.2% had a previous COVID-19 infection. The primary outcome occurred in 32.9% of respondents in parallel to 13% new pharmacological treatments for insomnia. The sleep quality worsened for 61.4%, while 43.5% and 22.8% reported ≥1-hour sleep duration reduction and worsening or new-onset nightmares, respectively. Multivariate analyses showed that age (OR:1.008; 95% CI 1.001-1.015), females (OR:1.590; 95% CI 1.335-1.900), weight change (decrease: OR:1.772; 95% CI 1.453-2.161; increase: OR:1.468; 95% CI 1.249-1.728), prevalent anxiety (OR:3.414; 95% CI 2.954-3.948), new-onset burnout (OR:1.761; 95% CI 1.489-2.083), family income reduction >30% (OR:1.288; 95% CI 1.069-1.553) and assisting patients with COVID-19 (OR:1.275; 95% CI 1.081-1.506) were independently associated with new-onset or worsening of previous insomnia episodes. CONCLUSIONS We observed a huge burden of insomnia episodes and other sleep disturbances in health care professionals during the COVID-19 pandemic.

Objective This review aimed to analyze the association of chronotype with dietary habits, namely energy and macronutrient intakes, meal timing, and eating patterns, as well as with obesity. Data Sources PubMed/MEDLINE, LILACS, and Google Scholar databases were searched between 2004 and 2020. Study selection was performed by 2 authors independently; disagreements on eligibility of articles were resolved by a third author. After assessment of 12 060 abstracts, 43 studies (21 articles on obesity; 13 on food consumption, meal timing, and eating patterns; and 9 that addressed both obesity and dietary behavior) were included. Data Extraction A standard form was used to extract study design, country, number of participants, method of chronotype determination, and main findings. Data A...

In particular, the question of whether sexual activity or fertility variations drive birth seasonality has remained open and challenging to test without large-scale data on sexual activity 2,3. Analyzing data from half-a-million users worldwide collected from the female health tracking app Clue combined with birth records, we inferred that birth seasonality is primarily driven by seasonal fertility, yet increased sexual activity around holidays explains minor peaks in the birth curve. Our data came from locations in the Northern Hemisphere (UK, US, and France) and the Southern Hemisphere (Brazil). We found that fertility peaks between the autumn equinox and winter solstice in the Northern Hemisphere locations and shortly following the winter solstice in the Southern Hemisphere locations.

Daily life has also altered people's eating habits, mainly among those who stayed working at home. However, changes in the eating habits of workers who remained working during the pandemic are still unknown. The aim of this study was to evaluate the impact of the COVID-19 pandemic on the dietary habits of day and shift workers from a condominium management company, as well as to measure adherence to a nutritional counseling program and its effect on workers' food intake and body weight. One hundred and fifty-one workers (77.5% of day workers and 22.5% of shift workers) were followed up in the pre-pandemic period and during the pandemic. Data on anthropometry, food consumption, and adherence to nutritional counseling were collected during nutritional meetings, which focused on qualitative modification of food intake and control of energy consumption. The rate of adherence to the program did...
