Preconception to postpartum accelerometry-based 24-hour movement behaviors
ClinicalTrials.gov, NCT03531658 (registered May 22, 2018)
Associations Among Physical Activity, Leukocyte Telomere Length, and Depression in Pregnancy
The prospective associations of 24-hour movement behaviors and domain-specific activities with executive function and academic achievement among school-aged children in Singapore
Background Physical activity (PA), sedentary behavior (SB), and sleep are collectively referred to as 24-h movement behaviors, which may be linked to cognitive development in children. However, most of the evidence was based on cross-sectional studies and/or solely relied on parent-reported information on children’s behaviors, and it remains uncertain whether all domains/contexts of PA and SB are similarly associated with executive function and a…
Correlates of lifestyle patterns among children in Singapore aged 10 years
These findings provide direction for future interventions by identifying vulnerable groups and contexts that should be prioritised
H Activity Guidelines in Children and Adolescents
This study aimed to examine the prevalence of adherence to 24 h activity guidelines in children and adolescents from Asia-Pacific cities. In 1139 children aged 5-18 years, moderate-to-vigorous physical activity (MVPA), screen viewing time (SVT), sleep duration, child weight, height, sex, and age were parent-reported. Descriptive statistics were used to assess the number of guidelines met, and prevalence of adherence to activity guidelines by city…
Evaluating the influence of low birth weight on food parenting practices in preschool children
Exploring how socioeconomic status affects neighbourhood environments’ effects on obesity risks
Research on how socioeconomic status interacts with neighbourhood characteristics to influence disparities in obesity outcomes is currently limited by residential segregation-induced structural confounding, a lack of empirical studies outside the U.S. and other ‘Western’ contexts, and an over-reliance on cross-sectional analyses. This study addresses these challenges by examining how socioeconomic status modifies the effect of accumulated exposur…
Automated Machine Learning (AutoML)-Derived Preconception Predictive Risk Model to Guide Early Intervention for Gestational Diabetes Mellitus
The increasing prevalence of gestational diabetes mellitus (GDM) is contributing to the rising global burden of type 2 diabetes (T2D) and intergenerational cycle of chronic metabolic disorders. Primary lifestyle interventions to manage GDM, including second trimester dietary and exercise guidance, have met with limited success due to late implementation, poor adherence and generic guidelines. In this study, we aimed to build a preconception-based…
Maternal meal irregularities during pregnancy and lifestyle correlates
Meal regularity can influence metabolic health. However, habits of skipping and delaying meals are rarely studied among pregnant women. This study examined the incidence of maternal meal skipping and meal delaying, and their associated lifestyle patterns during pregnancy. Pregnant women in the second trimester (18-24 weeks' gestation; n = 90) were recruited from the antenatal clinics in KK Women's and Children's Hospital, Singapore, 2019-2020. Da…
Associations of Childcare Arrangements with Adiposity Measures in a Multi-Ethnic Asian Cohort
Childcare arrangements shape behavioural patterns that influence the risk of childhood obesity. However, little is known of its influence on childhood obesity in Singapore. We aim to examine the associations between childcare arrangements at the age of 5 years and childhood adiposity at age 6 years. Children from the GUSTO study were grouped into three childcare arrangements at age 5: full-time centre-based childcare (FC), partial centre-based wi…
Identification and reproducibility of dietary patterns assessed with a FFQ among women planning pregnancy
Objective: To identify a posteriori dietary patterns among women planning pregnancy and assess the reproducibility of these patterns in a subsample using two dietary assessment methods. Design: A semi-quantitative FFQ was administered to women enrolled in the Singapore PREconception Study of long-Term maternal and child Outcomes study. Dietary patterns from the FFQ were identified using exploratory factor analysis (EFA). In a subsample of women (…
The Association of Different Types of Leisure Time Physical Activities with Cardiometabolic Outcomes in Singapore—Findings from the Multi-Ethnic Cohort Study
The study aimed to investigate the association between leisure time physical activity (LTPA) subtypes and cardiometabolic outcomes in the Singapore Multi-Ethnic Cohort (MEC). Self-reported data on socio-demographics, lifestyle factors , LTPA subtypes, and health screening data on body-mass index (BMI), waist circumference (WC), systolic and diastolic blood pressure (SBP and DBP), triglycerides (TG), and HDL-and LDL cholesterol were collected. Mul…

Iron status and risk factors of iron deficiency among pregnant women in Singapore
NCT01174875 . Registered 1 July 2010 (retrospectively registered)
Psychometric validation of the Japanese version of Alcohol Quality of Life Scale (AQoLS-Japan) in the treatment of patients with alcohol use disorder
The AQoLS-Japan is a reliable and valid measure of HR-QoL that is able to demonstrate benefits associated with the routine treatment of AUD in Japan
Validation of a semi-quantitative FFQ for 18-month-old toddlers
Objective Dietary intake of toddlers has been of growing interest due to its long-term consequences on health. However, previous works have focused largely on Caucasian populations and less is known about Asian toddlers. We aimed to validate a semi-quantitative FFQ designed to assess dietary intakes of 18-month-old toddlers in a multi-ethnic Asian cohort. Design An FFQ of ninety-four food items, identified based on food records of 12-month-old GU…
Maternal feeding practices and children's food intake during an ad libitum buffet meal
Prospective associations between parental feeding practices and children's oral processing behaviours
Previous research demonstrated that faster eating rates are linked with increased intake of energy during a meal. Here, we examined whether within-meal parental feeding practices show cross-sectional and prospective associations with children's oral processing behaviours and whether the previously demonstrated association between faster eating rates and higher energy intakes varies by parental feeding practices. A subset (n = 155) of children and…
Food Sources of Energy and Macronutrient Intakes among Infants from 6 to 12 Months of Age
Adequate nutrition during complementary feeding is important for the growth, development and well-being of children. We aim to examine the energy and macronutrient intake composition and their main food sources in a mother-offspring cohort study in Singapore. The diets of infants were assessed by 24 h dietary recalls or food diaries collected from mothers when their offspring were 6 (n = 760), 9 (n = 893) and 12 (n = 907) months of age. Food sour…
Oral processing behaviours that promote children's energy intake are associated with parent-reported appetitive traits
Sleep and Dietary Patterns in Pregnancy
Evidence on the association between sleep, diet, and eating behaviors in pregnant women is lacking. We examine this in a cohort of apparently healthy pregnant women. At 26-28 weeks gestation, 497 participants completed the Pittsburgh Sleep Quality Index to assess sleep and a 24-h recall to assess dietary intake. Diet quality was assessed by the Healthy Eating Index for pregnant women in Singapore (HEI-SGP) score and previously derived dietary pat…
Patterns of physical activity and sedentary behavior in a representative sample of a multi-ethnic South-East Asian population
Our population-based study suggests a need to encourage overall physical activity but, particularly regular leisure-time exercise, especially among middle-aged, females and those with lower levels of education and full-time employment. Strategies targeting workplaces may be important to reduce high levels of sedentary behavior
Tobacco smoke exposure and respiratory morbidity in young children
Secondhand smoke exposure during the prenatal and postnatal periods is associated with increased respiratory morbidity in children. Opportunistic screening and targeted smoking cessation counselling for parents at child hospital admissions and well-child outpatient visits, as well as preconception smoking cessation counselling for future pregnancies, may be beneficial to protect the child from negative health impacts
Dietary changes during pregnancy and the postpartum period in Singaporean Chinese, Malay and Indian women
Objective To examine changes in food consumption during pregnancy and the postpartum period in women of major Asian ethnic groups. Design Using interviewer-administered questionnaires, we assessed changes in food consumption during pregnancy (26–28 weeks’ gestation) and the postpartum period (3 weeks after delivery) as compared with the usual pre-pregnancy diet. Setting Singapore. Subjects Pregnant women ( n 1027) of Chinese, Malay and Indian eth…
