Proportions and trends of global adolescent knowledge and attitudes toward tobacco smoking from 1999 to 2019
Objective We aimed to assess the recent levels of knowledge and attitudes toward tobacco smoking among adolescents aged 12–16 years in 2010–2019, and to examine trends from 1999 to 2019. Methods We used the most recent data from 145 countries/territories (hereafter “countries”) that conducted at least one Global Youth Tobacco Survey (GYTS) between 2010 and 2019 to assess the current levels of knowledge and attitudes toward tobacco smoking among a…
Parental smoking is associated with adolescent loneliness
Introduction: The association between parental smoking and adolescent mental health is not well understood. We aimed to examine the association between parental smoking and adolescent loneliness using global data collected from the Global School-based Student Health Survey (GSHS) between 2009 and 2019. Methods: A total of 187,552 adolescents aged 12-15 years in 71 low- and middle-income countries (LMIC) from the GSHS with cross-sectional design w…
Proportion and trend in the age of cigarette smoking initiation among adolescent smoking experiencers aged 13–15 years in 148 countries/territories
Background: Limited studies have assessed the recent proportion and trend in the age of cigarette smoking initiation among adolescent smoking experiencers globally. We aimed to assess the recent global proportion, associated factors and the long-term trend of the initiated age of cigarette smoking among adolescent smoking experiencers. Methods: We used data from the most recent Global Youth Tobacco Survey on 99,728 adolescent smoking experiencers…
Prevalence of waterpipe smoking and its associated factors among adolescents aged 12–16 years in 73 countries/territories
Introduction: To describe the recent prevalence of, and trends in, waterpipe smoking and to examine its associated factors among adolescents aged 12-16 years in 73 countries/territories (hereafter "countries"). Methods: Data from 72 countries that had conducted a Global Youth Tobacco Survey (GYTS) in 2010-2019 and from the National Youth Tobacco Survey in the United States in 2019 were used to assess the recent prevalence of waterpipe smoking and…
Measuring Hypertension Progression With Transition Probabilities
This paper assessed the transition probabilities between the stages of hypertension severity and the length of time an individual might spend at a particular disease state using the new American College of Cardiology/American Heart Association hypertension blood pressure guidelines. Data for this study were drawn from the Ghana WHO SAGE longitudinal study, with an analytical sample of 1884 across two waves. Using a multistate Markov model, we est…
Prevalence of thinness, overweight and obesity among Tibetan adolescents aged 12–17 years
Objective: To estimate the prevalence of thinness, overweight and obesity among Tibetan adolescents aged 12–17 years. Design: Cross-sectional survey. Setting: Shigatse City of Tibet municipality, with an average altitude of more than 4000 m. Participants: Study participants included 2642 adolescents aged 12–17 years selected from six schools using a convenient cluster sampling method. Results: The prevalence of thinness/overweight/obesity among T…
Association of sleep duration with all-cause and disease-specific mortality in US adults
BACKGROUND: Previous studies revealed inconsistent findings regarding the association between sleep duration and all-cause and disease-specific mortality. This study aimed to clarify the association of sleep duration with mortality using a large population-based prospective cohort study from the USA. METHODS: We used data from the National Health Interview Survey (2004-2014) linked to National Death Index records to 31 December 2015. A total of 2…
Impact of overweight and obesity on life expectancy, quality-adjusted life years and lifetime costs in the adult population of Ghana
INTRODUCTION: Prior studies have revealed the increasing prevalence of obesity and its associated health effects among ageing adults in resource poor countries. However, no study has examined the long-term and economic impact of overweight and obesity in sub-Saharan Africa. Therefore, we quantified the long-term impact of overweight and obesity on life expectancy (LE), quality-adjusted life years (QALYs) and total direct healthcare costs. METHODS…
Light Cigarette Smoking Increases Risk of All-Cause and Cause-Specific Mortality
Very few studies have examined the association between light cigarette smoking (i.e., ≤5 cigarettes per day) and mortality. The aim of this study was to examine the association of light cigarette smoking with all-cause and cause-specific mortality among adults in the United States. Data were from 13 waves of the National Health Interview Survey (1997 to 2009) that were linked to the National Death Index records through December 31, 2011. A total …
Health service utilization and direct healthcare costs associated with obesity in older adult population in Ghana
Obesity is a major risk factor for many chronic diseases and disabilities, with severe implications on morbidity and mortality among older adults. With an increasing prevalence of obesity among older adults in Ghana, it has become necessary to develop cost-effective strategies for its management and prevention. However, developing such strategies is challenging as body mass index (BMI)-specific utilization and costs required for cost-effectivenes…
Psychological distress and mortality among US adults
BACKGROUND: Previous studies have shown inconsistent findings on the association between psychological distress and risk of mortality. This study aimed to address this inconsistent association using a large US population-based cohort. METHODS: This study used data from 1997 to 2009 US National Health Interview Survey, which were linked with National Death Index through 31 December 2011. Psychological distress was measured using Kessler-6 scale an…
Annual transition probabilities of overweight and obesity in older adults
Smoking and Physical Activity Trajectories from Childhood to Midlife
Introduction: Despite substantial interest in the development of health behaviors, there is limited research that has examined the longitudinal relationship between physical activity (PA) and smoking trajectories from youth to adulthood in a Finnish population. This study aimed to identify trajectories of smoking and PA for males and females, and study the relationship between these trajectories from youth to adulthood. Methods: Latent profile an…
Changes in Daily Steps and Body Mass Index and Waist to Height Ratio during Four Year Follow-Up in Adults
Aims: Over the study years, there was a significant increase in body mass index (BMI) and waist-to-height ratio (WtHR) in middle aged Finnish adults. Methods: Data were obtained from 1033 Finnish adults from the Cardiovascular Risk in Young Finns Study in 2007 and 2011. Cohort study participants wore an Omron Walking Style One (HJ-152R-E) pedometer for five days and were grouped into those who increased, maintained and decreased their steps betwe…
Childhood Adiposity, Adult Adiposity, and Cardiovascular Risk Factors
BACKGROUND: Obesity in childhood is associated with increased cardiovascular risk. It is uncertain whether this risk is attenuated in persons who are overweight or obese as children but not obese as adults. METHODS: We analyzed data from four prospective cohort studies that measured childhood and adult body-mass index (BMI, the weight in kilograms divided by the square of the height in meters). The mean length of follow-up was 23 years. To define…
