AI Article Synopsis
- The study aimed to analyze trends in risk and protective behaviors related to chronic noncommunicable diseases among Brazilian adolescents using data from the National School Health Survey conducted in 2009, 2012, and 2015.
- Researchers surveyed over 173,000 ninth-grade students, assessing factors like diet, physical activity, and substance use through linear regression.
- Despite improvements in fruit consumption and reductions in unhealthy behaviors, there was a concerning increase in illicit drug use, highlighting the need for effective school health promotion programs.
Article Abstract
Objective: To analyze trend estimates on the prevalence of risk and protective behaviors for chronic noncommunicable diseases in adolescents, according to data from the National School Health Survey in 2009, 2012 and 2015.
Methods: Data from the three cross-sectional studies in Brazilian capitals and the Federal District were used. In total, 173,310 adolescents enrolled in the ninth grade of elementary school were interviewed, with average age of 14 years. The prevalence of indicators of protective (consumption of beans and fruit; physical education classes at school; practice of physical activity for 60 minutes or more) and risk factors (consumption of candies and soft drinks; use of cigarettes and alcohol in the last 30 days; drug testing) were estimated through linear regression.
Results: There was a significant increase (p < 0.05) in the prevalence of fruit consumption and in the reduction of bean, soft drinks and candies consumption, as well as the consumption of alcoholic beverages and cigarettes. However, an increase in the prevalence of illicit drug experimentation was observed. Discussion: Despite the tendency to reduce risk factors, prevalences are high when compared with other sociocultural realities.
Conclusion: The school is an important area of access to the adolescent public, and it is necessary to encourage school health promotion programs to reduce health risk behaviors, as well as to stimulate protective ones.

Pathways to Hypertension Control: Unfinished Journeys of Low-Income Individuals in Malaysia and the Philippines.

Centre for Global Chronic Conditions, London School of Hygiene & Tropical Medicine, London, UK.
Background: Reducing inequities in hypertension control among those affected in low- and middle-income countries requires person-centred health system responses based on a contextualised understanding of the choices and care pathways taken by those who rely on the services provided, particularly those from poor and marginalised communities. We examine patterns of care seeking and pathways followed by individuals with hypertension from low-income households in the Philippines and Malaysia. This study aims to fill a significant gap in the literature by analysing the stages at which individuals make decisions that may affect the successful control of their blood pressure.

Aim: Hypothyroidism is created by disruption of thyroid hormone production, which can destroy the emotional, relational, social, and working life of patients if left untreated. Hypothyroidism has multiple etiologies. We evaluated the relationship of hematological parameters and inflammatory biomarkers with thyroid hormones to find the potential use of these items in patients screening and prognosis.

Background: The prevalence of hypertension among the Tibetan population in Tibet is higher than in other regions of China, and there is a lack of unified epidemiological surveys. This study aims to conduct a standardized epidemiological investigation to assess the current status of hypertension among the Tibetan population, as well as to explore the dose-response relationship between cholesterol (TC), triglyceride glucose index (TyG), triglyceride glucose-body mass index (TyG-BMI), and hypertension in this population.
Methods: From June 2020 to July 2023, a total of 5042 Tibetans aged 18 to 80 years from three cities and one region in Tibet were randomly sampled for the study.

Department of Physical Education, Kyung Hee University, Yongin-si, Gyeonggi-do, Korea.
Background: Non-communicable diseases (NCDs) are a major global health challenge and occupational status is a critical determinant influencing NCD development, yet many cross-sectional studies have only linked current occupational status with specific diseases, overlooking broader temporal factors. The primary aim of the present study was to comprehensively elucidate the intricate interplay between alterations in working status, NCDs, and physical activity (PA) among Korean middle-aged and older adults, employing a longitudinal panel study design.
Methods: This study utilized longitudinal data from the Korean Longitudinal Study of Aging, covering the period from 2006 to 2020, with a median follow-up duration of 10 years.

The phenomenon of population aging in China has evolved into an irreversible trend. The state places significant emphasis on the health-related initiatives for the elderly and has implemented pertinent policies. This study aims to identify the primary health issues affecting the elderly population in China, ascertain the key risk factors influencing their health, and offer a scientific foundation for the government to develop ongoing policies and strategies, as well as to allocate health resources efficiently.
