Socioeconomic disadvantages over the life-course and their influence on obesity among older Hong Kong Chinese adults

The life-course perspective on socioeconomic inequality in health is a burgeoning field of research. Nonetheless, the three classic life-course models (i.e. sensitive period, cumulative risk and social mobility models) have rarely been simultaneously applied to studies on obesity. Therefore, this study examined the associations of socioeconomic positions (SEPs) across life stages and their associated life-course models with both general and abdominal obesity. Face-to-face interviews were conducted among 1077 community-dwelling adults aged 50 or above during 2014-15 in Hong Kong. Experiences of poverty, educational attainment and deprivation of necessities represented respondents' SEP in childhood, early adulthood and late adulthood, respectively. General and abdominal obesity were defined as body mass index ≥25 kg m-2 and waist-to-height ratio >0.5. Multivariable modified Poisson regression with a robust error variance was performed. Respondents with low childhood SEP tended to have reduced risk of general obesity [relative risk (RR) = 0.85; 95% confidence interval (CI) = 0.72-1.00], whereas those with low childhood SEP and low late-adulthood SEP tended to have increased risk of abdominal obesity (RR = 1.10; 95% CI = 1.00-1.21 ...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.
