Body mass index trajectories and all-cause mortality in older Chinese adults
BACKGROUND: Weight loss at older ages appears to be associated with higher mortality in Western and some East Asian countries, despite differences in the prevalence of obesity; whether it is relevant to China is unknown. We examined the association of body mass index (BMI) trajectories with all-cause mortality in older Chinese adults by sex and baseline age (65-69 years, 70+ years). METHODS: 54 160 participants aged 65 or above from Hong Kong's E…
Association of childhood food consumption and dietary pattern with cardiometabolic risk factors and metabolomics in late adolescence
BACKGROUND: Healthy diet might protect against cardiometabolic diseases, but uncertainty exists about its definition and role in adolescence. METHOD: In a subset of Hong Kong's 'Children of 1997' birth cohort (n=2844 out of 8327), we prospectively examined sex-specific associations of food consumption and dietary pattern, proxied by the Global Diet Quality Score (GDQS) at~12.0 years, with cardiometabolic risk factors and metabolomics at~17.6 year…
Relative Deprivation, Income Inequality, and Cardiovascular Health
The associations between absolute vs. relative income at the household or neighborhood level and cardiovascular disease (CVD) risk remain understudied in the Chinese context. Further, it is unclear whether stress biomarkers, such as cortisol, are on the pathway from income to CVD risk. We examined the associations of absolute and relative income with CVD risk observationally, as well as the mediating role of cortisol, and validated the role of co…
Pubertal testis volume, age at pubertal onset, and adolescent blood pressure
OBJECTIVES: A warning from Health Canada suggests that testosterone increases blood pressure (BP). No evidence from large randomized controlled trials is available, and observational studies are confounded by ill-health lowering serum testosterone. To address the evidence gap, we assessed the association of pubertal testicular volume, as a reflection of testosterone production, with BP. METHODS: We examined whether testicular volume was associate…
The association of breastfeeding with insulin resistance at 17 years
Breastfeeding has many benefits for mother and infant. Whether breastfeeding also protects against type 2 diabetes is unclear. To clarify the role of breastfeeding in type 2 diabetes, we assessed the association of breastfeeding with insulin resistance in late adolescence in a birth cohort from a non-Western setting where breastfeeding was not associated with higher socio-economic position. We used multivariable linear regression, with multiple i…
Age–period–cohort analysis of trends in blood pressure and body mass index in children and adolescents in Hong Kong
BACKGROUND: The declining or fluctuating trend in blood pressure (BP) despite the rising trend in body mass index (BMI) during childhood and adolescence is unexplained. We decomposed trends in BP and BMI to identify the relevance of early-life and contemporaneous factors. METHODS: We assessed the relative contribution of age, period and cohort to secular trends in BP in children and adolescents (9-18 years) from 1999 to 2014 and BMI (6-18 years) …
Household income and adolescent blood pressure in a Chinese birth cohort
Spatial proximity and childhood hospital admissions in a densely populated conurbation
SP3-47 Spatial proximity and childhood hospital admissions in a densely populated conurbation
Introduction Physical distance is a barrier to hospital utilisation. In a very densely populated city in China, we examined whether use of public hospitals by children was associated with individual-level residential proximity, and whether these associations varied with type of admission. Methods The authors used multivariable negative binomial regression in a large, population-representative birth cohort to examine the adjusted associations of p…
P2-148 Early life infections and pubertal onset
Introduction With economic development, puberty occurs at younger ages, and may contribute to cardiovascular diseases and hormone-related cancers. Factors determining pubertal timing are poorly understood. The growth axis active during puberty is also active in the first 6 months of life and interacts with the immune system. Methods The authors examined whether prior infections, proxied by number of hospital episodes for infections at different a…
O1-5.3 The role of milk and dairy products in childhood obesity
Introduction Observational studies, mainly from western populations, suggest that dairy product consumption is inversely associated with adiposity. However, in such populations, there is a limited range of dairy product intake while dietary intake and obesity share social patterning making evidence from non-western developed settings valuable in distinguishing whether the observed associations are biologically mediated or socially confounded. Met…
Early life second-hand smoke exposure and serious infectious morbidity during the first 8 years
Household SHS exposure in early infancy increases severe infectious morbidity requiring hospital admission. Reducing SHS exposure in infants and particularly in more vulnerable infants will lower the bed-days burden due to infectious causes
