This cross-sectional study analyzed the association between physical activity (PA) and social jetlag (SJL) among shift workers. We evaluated 423 employees, aged between 18 and 60 years, who worked in a poultry-processing company in Brazil. Physical activity levels (PAL) were determined by the short form of the International Physical Activity Questionnaire (IPAQ-SF). SJL was calculated as the absolute difference between the time of mid-sleep on work and free days. The percentage of workers insufficiently active was high on all shifts, with no significant differences between the 3 shifts. The amount of time spent in sedentary behavior on workdays did not differ between shifts. Among night-shift workers, negative associations were observed between SJL and 1) the duration and weekly energy expenditure while walking; 2) the frequency of moderate and vigorous PA; and 3) the total energy expenditure related to PA. Even though PAL did not differ among workers on different shifts, we found a high prevalence of subjects who were insufficiently active or too sedentary among all groups. Also, SJL was negatively associated with PA in night-shift workers. These results suggest that PA should be encouraged among shift workers and that SJL may be an important factor in reducing PA in this cohort.

Noninjecting illicit drug users (NIDUs) present high risk for HIV infection, due especially to transactional sex. This study aimed to estimate the prevalence and risk factors for transactional sex among NIDUs in the Southwest region of Goiás State, Central Brazil. The prevalence of self-reported transactional sex was 22.8%. Prevalence in women and men was 52.7% and 16.8%, respectively, a significant difference (p < 0.001). Crack use and history of sexually transmitted infections (STI) were risk factors for transactional sex in men. Homelessness, crack use, sex under the influence of drugs, and history of sexual violence were risk factors for transactional sex in women. A high prevalence of transactional sex was observed among NIDUs. This risk behavior may contribute to the high rates of HIV among this population and their social networks and in the general population.

Objective:To calculate the prevalence and analyze factors associated with tobacco use once in a lifetime and check their harmful use among pregnant women. Methods: Cross-sectional study conducted with 330 pregnant women assisted in specialized center for women primary health care (Central Brazil). The data of personal/family history and tracing of tobacco use were obtained through a sociodemographic questionnaire (Alcohol, Smoke and Substance Involvement Screening Test) and analyzed using logistic regression. Results: The use of tobacco once in a lifetime was associated with income, family history of alcohol and personal mental disorder. The harmful use of tobacco during pregnancy was associated with a family history of smoking and alcohol consumption. Conclusion: The prevalence of tobacco use as "once in a lifetime" in the sample was 37.1% (124) and "harmful use" of tobacco during pregnancy was 9.6% (32). ResumoObjetivo: Calcular a prevalência e analisar os fatores associados ao uso de tabaco uma vez na vida e verificar o seu uso nocivo entre gestantes. Métodos: Estudo transversal em 330 gestantes atendidas em centro especializado no atendimento à saúde das mulheres na atenção básica (Brasil Central). Os dados dos antecedentes pessoais/familiares e o rastreamento de uso de tabaco foram obtidos por meio de questionário sociodemográfico (Alcohol, Smokeand Substance Involvement Screening Test) e analisados usando regressão logística. Resultados: O uso de tabaco uma vez na vida mostrou estar associado à renda, antecedentes familiares de consumo de álcool e pessoais de transtorno mental. O uso nocivo de tabaco durante a gestação foi associado a antecedentes familiares de tabagismo e consumo de álcool. Conclusão: A prevalência de uso de tabaco uma "vez na vida" na amostra estudada foi de 37,1% (124) e "uso nocivo" de tabaco na gestação foi de 9,6% (32).

Objective: this integrative literature review aimed to systematize scientific production regarding the process of aging, mental health, and suicide. Method: the LILACS, MEDLINE, and PubMed databases were used to search for papers published between 2007 and 2017. The final analysis included 34 papers. Result: descriptive North American studies in English were most prevalent. The largest number of papers on the theme was published in 2013. The researchers used questionnaires and interviews as instruments for questions involving aging and suicidal ideation. The papers revealed an association of suicide or suicidal ideation in elderly persons who manifested anxiety, depressive symptoms, depression, physical diseases, low educational and socioeconomic levels, and chronic diseases. Conclusion: this integrative review reinforces the need for investment in public policies and spaces that offer receptiveness, listening, and safety for the aged population, as well as surveys with more robust methodologies to investigate the phenomenon under analysis.

Factors associated with the probability of common mental disorders in pregnant women: a cross-sectional study AbstrActObjective: To estimate the prevalence of probability of common mental disorders in pregnant women and associated factors. Methods:A cross-sectional study with a quantitative and descriptive approach was performed with 330 pregnant women enrolled in a Women's Health Service located in Mid-West Brazil. Data were obtained through a questionnaire about socio-demographic characteristics and family or personal history. The Self-Reporting Questionnaire and Poisson regression were applied to screen for common mental disorders, aiming to identify factors associated with it. Results: The prevalence of probability of common mental disorders among pregnant women was 57.1% and it was associated with marital status, gestational age, unplanned pregnancy and bleeding. Conclusion: The prevalence of pregnant women likely to have common mental disorders and the average Self-Reporting Questionnaire score estimated in this study were higher than those found in other studies with samples from the general population.
