The impact of cultural identity, parental communication, and peer influence on substance use among Indigenous youth in Canada.

Heavy drinking and smoking have been found to be among the leading causes of morbidity and mortality within Indigenous youth in North America. The focus of this study was to examine the relative roles of cultural identity, parent-child communication about the harms of substance use (SU), and perception about peers' opinions on heavy drinking and cigarette smoking among Indigenous youth. Strong Indigenous cultural identity, parent-child communication about SU, and affiliation with peers who do not use and/or who disapprove of substance use were all expected to reduce risk for heavy drinking and smoking.

Association between Arterial Hypertension and Laboratory Markers, Body Composition, Obstructive Sleep Apnea and Autonomic Parameters in Obese Patients.

Background: Systemic arterial hypertension (SAH) is a multifactorial disease, highly prevalent and associated with health risks.

Objective: The purpose of this study was to investigate the association between SAH and laboratory, anthropometric, heart rate variability (HRV), and obstructive sleep apnea markers and, secondarily, to analyze the sensitivity and specificity of the variables that are independent factors in the association.

Methods: Cross-sectional study with 95 obese patients treated at an obesity referral clinic in Salvador, BA, Brazil.

Cost-effectiveness of home care services versus hospital care for pediatric patients worldwide: A protocol for systematic review and meta-analysis.

Background: Despite the expansion of home care services (HCS) in several countries, there is still a need to systematically investigate the available evidence on the cost-effectiveness of this type of service compared to hospital care in the world, particularly for the pediatric population. Hence, we aimed to systematically synthesize and critically evaluate the evidence on the cost-effectiveness of HCS versus in-hospital services worldwide.

Methods: A systematic review and meta-analysis protocol guided by Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols.

Molecular aspects of COVID-19 and its relationship with obesity and physical activity: a narrative review.

Background: Severe acute respiratory syndrome coronavirus 2 has several mechanisms of action related to inflammatory responses, especially in individuals diagnosed with obesity. This hyperinflammatory clinical profile resulting from the association between obesity and coronavirus disease 2019 (COVID-19) may be attenuated by regular physical activity.

Objective: The aim of this study was to review the evidence on the consequences of physical inactivity and physical activity on COVID-19 in patients with obesity.

Anthropometric Measures for the Prognosis of Obstructive Sleep Apnea in Obese.

Objective: The objective of this study was to identify, among the different anthropometric indicators, the one that shows higher discriminatory power for the prognosis of Obstructive Sleep Apnea Syndrome (OSAS).

Design: Observational cross-sectional study PARTICIPANTS: Obese individuals elective to bariatric surgery METHODS: A study based on data of 758 patients aged ≥ 21 years old, of both sexes, in the pre-operatory stage of the surgical procedure of gastric bypass. Obstructive sleep apnea and obstructive sleep hypopnea were evaluated and classified through the apnea-hypopnea index, which was obtained through the examination of polysomnography.
