Background: Globally, some 45 million children under five years of age are wasted (low weight-for-height). Although 2023 World Health Organisation guidelines on their care did not aim to identify optimal weight gain, they did mention 5-10 g/kg/day as a target, which is a change from prior guidelines that recommended 10-15 g/kg/day, when inpatient-only care was the norm. We aimed to inform future policy/programming on weight gain targets.

Introduction: Very little is known about the longitudinal associations between physical activity and obesity in Latin America. Therefore, the purpose of this study was to investigate associations of leisure-time physical activity with abdominal and general obesity in adults in Mexico.

Methods: Participants in the Mexico City Prospective Study were surveyed from 1998 to 2004 and resurveyed from 2015 to 2019.

Unhealthy lifestyles risk factors, such as smoking, alcohol consumption, physical inactivity, poor diet, and obesity, have been associated with a higher risk of all-cause and cause-specific mortality. However, composite score of these unhealthy behaviours has not been considered, particularly in Latin American populations. Herein, we examined the association of lifestyle risk factors score with all-cause and cause-specific mortality in Mexican adults.

Background: There is limited population-based evidence on the prevalence of cognitive impairment in Mexico, a country with a rapidly aging population and where key risk factors, such as diabetes and obesity, are common. This study describes the distribution of cognitive impairment in adults from Mexico City.

Methods: This cross-sectional population-based study included participants from the Mexico City Prospective Study which recruited 150,000 adults aged ≥ 35 years in 1998-2004.

Article Synopsis
  • - This study aimed to examine the relationship between the 'weekend warrior' physical activity pattern (exercising once or twice a week) and the risk of mild dementia among adults.
  • - Data from 10,033 participants in Mexico City were analyzed over a follow-up period of 16 years, revealing that 'weekend warriors' had a lower risk of mild dementia compared to those who did not exercise.
  • - The findings suggest that even minimal physical activity, like that of weekend warriors, may help reduce the risk of mild dementia, indicating potential benefits for mental health.

Article Synopsis
  • The study explored the long-term relationship between physical activity levels and obesity in Colombian adults from 2005 to 2019, recognizing that many engage in light physical activities vital for daily life.
  • Participants were categorized by their weekly physical activity measured in MET minutes, with obesity defined as having a BMI of 30 or higher, and factors like age, sex, and diet were controlled in the analysis.
  • Results indicated that higher physical activity levels (medium and high) were linked to lower odds of obesity compared to low activity levels, suggesting that even busy individuals in Colombia can lower their obesity risk by increasing physical activity.

Aim: To investigate the joint associations of diabetes and obesity with all-cause and cardiovascular disease (CVD) mortality in the Mexico City Prospective Study.

Materials And Methods: In total, 154 128 participants (67.2% women) were included in this prospective analysis.

Background: We examined the association between individual lifestyle risk factors with all-cause and cause-specific mortality.

Methods: Prospective cohort study including 155,002 participants from the Mexico City Prospective Study. Cox regression models were used to estimate the association between individual lifestyle risk factors and all-cause and cause-specific mortality.

Objectives: The objective was to investigate the benefits of the 'weekend warrior' physical activity pattern in Latin America, where many people take part in high levels of non-exercise physical activity.

Methods: Participants in the Mexico City Prospective Study were surveyed from 1998 to 2004 and resurveyed from 2015 to 2019. Those who exercised up to once or twice per week were termed weekend warriors.

Background: Controversies exist on whether the presence of cardiovascular risk factors and their association with major cardiovascular events (MACE) is different between men and women. Most of the evidence comes from high-income countries, hindering extrapolation of sociocultural and demographic factors of other regions.

Objective: To evaluate sex differences in the prevalence of cardiovascular risk factors and the incidence of MACE and diabetes in Colombian adults.

Background: Studies in the West suggest that tombstone cost is associated with longevity. The objective of this observational study was to investigate the association between tombstone cost and longevity in a large cemetery in Latin America.

Methods: Age at death was obtained from 2,273 consecutive death certificates held at the San Pedro Cemetery Museum in Medellín in Colombia.

Background: Cable cars are part of the transport system in several cities in Latin America, but no evaluations of their effects on physical activity are available. TransMiCable is the first cable car in Bogotá, Colombia, and the wider intervention includes renovated parks and playgrounds. We assessed the effects of TransMiCable and the wider intervention on physical activity.

Global initiatives call for further understanding of the impact of inequity on aging across underserved populations. Previous research in low- and middle-income countries (LMICs) presents limitations in assessing combined sources of inequity and outcomes (i.e.

Background: Mild cognitive impairment often precedes dementia. The purpose of this analysis was to estimate the population attributable fraction for physical activity in Colombia, which is the reduction in cases that would occur if all participants were physically active.

Methods: The sample included 20,174 men and women aged 70.

Background And Objective: More research is required to understand associations of body mass index (BMI) and sarcopenia with cognition, especially in Latin America. The objective of this study was to investigate associations of BMI and sarcopenia with mild cognitive impairment in Colombia.

Design Setting And Participants: Data were from the National Survey of Health, Wellbeing and Aging in Colombia (SABE Colombia, in Spanish).

Alcohol drinking and risk factors for problematic drinking may vary across a lifespan. The objective of this study was to identify risk factors for problematic drinking in men and women in their thirties and forties. Alcohol drinking and potential risk factors for problematic drinking were assessed at ages 30, 34, 42, and 46 in the 1970 British Cohort Study.

Our objective was to investigate longitudinal associations between alcohol drinking and body mass index (BMI). Alcohol drinking (exposure), BMI (outcome), smoking habit, occupation, longstanding illness, and leisure time physical activity (potential confounders) were assessed at ages 30, 34, 42, and 46 in the 1970 British Birth Cohort Study. Multilevel models were used to cope with the problem of correlated observations.

The objective of this study was to investigate associations between education in early life and cognitive impairment in later life in Colombia. Participants were community-dwelling adults aged 60 years or older from the National Study of Health, Wellbeing and Ageing. Trained interviewers administered a shorter version of the mini-mental state examination.

Understanding the associations between types of alcoholic drinks and adiposity has public health relevance, considering that adult overweight and obesity prevalence are increasing worldwide. We aimed to evaluate the association between overall alcohol consumption and types of alcohol drinks with markers of adiposity from the UK Biobank baseline data ( = 280,183, 48.3% female).

Background: Associations of cardiorespiratory fitness in childhood and adulthood with adult cardiometabolic risk factors are poorly understood, not least because of the paucity of studies.

Objectives: We investigated associations between nonexercise testing cardiorespiratory fitness (NETCRF) in childhood/adulthood and cardiometabolic risk factors in adulthood.

Methods: Based on an established algorithm comprising gender, age, body mass index, resting heart rate, and self-reported physical activity at age 10, we computed NETCRF.

Physical activity is thought to be cardioprotective, but associations with different subtypes of cardiovascular disease (CVD) are poorly understood. We examined associations between physical activity and seven major CVD death causes. The sample comprised 65,093 adults (aged 58 ± 12 years, 45.
