Spatial inequalities in urban infrastructure for physical activity in Greater Santiago, Chile
This study characterized urban infrastructure (UI) supporting physical activity (PA) in Greater Santiago (GS), Chile, and examined its spatial distribution. A conceptual model comprising four key dimensions — active transport, green areas, public transport, and safety — was used to guide selection of relevant indicators (23 total). Statistical and spatial analyses were conducted across 34 municipalities and 1623 neighborhoods using a summary inde…
Associations between social and built environments and cardiovascular disease mortality across 342 Latin American cities
Background: Latin American cities have heterogeneous mortality and urban environment profiles. We aim to describe the variability in cardiovascular disease (CVD) mortality across and within cities, and within and between Latin American countries, and investigate the associations between urban environmental features and CVD mortality in these areas. Methods: Using harmonised data from the Salud Urbana en América Latina (i.e. Urban Health in Latin …
Are extensions in paid parental leave associated with lower infant and neonatal mortality in Latin American cities? Evidence from 148 cities in Chile, Mexico, and Colombia (2000-2015)
We examined changes in infant and neonatal mortality that occurred after extension in the minimum number of days of paid maternity leave and after the implementation of paid paternity leave in 148 cities using longitudinal city-level data (2000-2015) from Chile, Colombia, and Mexico, compiled and harmonized by the Salud Urbana en America Latina (SALURBAL) study. For Chile we also explored variations in these associations according to the mother's…
Modification of temperature-related human mortality by area-level socioeconomic and demographic characteristics in Latin American cities
Evidence of effect modification of cold-related mortality in Latin American cities was limited, and unexpected patterns of modification of heat-related mortality were observed. Socioeconomic deprivation may impact cold-related mortality, particularly among the elderly. The findings of higher levels of poverty and income inequality associated with lower heat-related mortality deserve further investigation given the increasing importance of urban a…
Cesarean sections and social inequalities in 305 cities of Latin America
We found large variability in CSR across cities highlighting the potential role of local policies on CSR levels. Variability was associated in part with maternal and area education and GDP. Further research is needed to understand the reasons for this pattern and any policy implications it may have
Aging and self-reported health in 114 Latin American cities
Across cities in Latin America, aging impact on health is significant among middle-aged adults, and among men. In both genders, cities with lower SEI or lower GDP per-capita were associated with poor SRH. More research is needed to better understand gender inequalities and how city socioeconomic environments, represented by different indicators, modify exposures and vulnerabilities associated with aging
Are Women’s Empowerment and Income Inequality Associated with Excess Weight in Latin American Cities
While income gradients and gender inequalities in excess weight have been noted elsewhere, data from Latin American cities is lacking. We analyzed gender-specific associations between city-level women's empowerment and income inequality with individual-level overweight/obesity, assessing how these associations vary by individual education or living conditions within cities in Latin America. Data came from national surveys and censuses, and was co…
One size does not fit all
Pregnancy-related metrics vary by race/ethnicity, yet most gestational weight gain (GWG) guidelines are ethnicity-blind. We estimated small-for-gestational age (SGA) risk in a Japanese population, examining GWG adequacy categorized by Institute of Medicine (IOM) and Japanese guidelines in male ( N = 192) and female ( N = 191) full-term singleton infants. For predicting SGA, IOM guidelines had high sensitivity ( ≥ 0.75), but low specificity ( ≤ 0.…
Differences in magnitude and rate of change in adult obesity distribution by age and sex in Mexico, Colombia and Peru, 2005–2010
Objective Unequal obesity distributions among adult populations have been reported in low- and middle-income countries, but mainly based on data of women of reproductive age. Moreover, incorporation of ever-changing skewed BMI distributions in analyses has been a challenge. Our study aimed to assess magnitude and rates of change in BMI distributions by age and sex. Design Shapes of BMI distributions were estimated for 2005 and 2010, and their cha…
Inadequate gestational weight gain increases risk of small‐for‐gestational‐age term birth in girls in Japan
OBJECTIVES: Babies born small for gestational age (SGA) have a higher risk of neonatal morbidity and mortality as well as later life chronic disease. The objectives of this study were to examine the extent to which prepregnancy body mass index (BMI) and gestational weight gain (GWG) influenced risk of SGA among Japanese, and to evaluate physician response to, and potential effects on, GWG. METHODS: We examined SGA risk as a function of maternal B…
