Associations between the Chronotypes and Eating Habits of Hong Kong School-Aged Children.

ABSTRACT: Later chronotypes have been found to be associated with unhealthy diets in adolescents and adults, but no study has been conducted in children. The aim of this study was to investigate the associations between the chronotypes and dietary patterns of school-aged children. Children aged 7-11 and their parents were recruited from five mainstream schools in Hong Kong. The parents were told to complete questionnaires on the children's circadian preferences, food frequency, and dietary behaviors. All of the questionnaires were distributed and collected by schoolteachers. No gender differences in chronotype were observed (all p > 0.05). The evening-type was associated with significantly greater odds of viewing television (TV) during meals (adjusted odds ratios (OR) = 5.62 in boys and 5.39 in girls). Evening-oriented boys were prone to skipping breakfast (adjusted OR = 14.78), whereas evening-oriented girls were at risk of consuming fast food (adjusted OR = 7.74). There are indications of some gender differences in chronotype-related eating patterns. Sleep duration and screen time significantly mediated the associations between later chronotypes and unhealthy eating habits. Individualized dietary recommendations in accordance with circadian preferences may be effective at promoting healthy and nutritious diets for school-aged children.

Project description:Childhood obesity is a global public health issue, including in the Chinese setting, and its prevalence has increased dramatically throughout the last decade. Since the origins of childhood obesity may lie in the pre-school period, factors relating to very young children's food consumption should be investigated. Parental influence, including feeding style, is the major determinant of childhood dietary behaviour through altering food provision and social environment. However, the applicability of previous research on parental feeding styles was limited by small sample size. To evaluate the influence of parental feeding styles on children's dietary patterns, a cross-sectional study was conducted among 4553 pre-schoolers in Hong Kong. Information was obtained about dietary intake and how regularly they had breakfast, using previous health surveillance surveys taken among primary school students. Parental feeding styles were assessed by a validated Parental Feeding Style Questionnaire and categorized into 'instrumental feeding', 'emotional feeding', 'prompting and encouragement to eat' and 'control over eating'. Multivariable analysis was performed, adjusted for demographic information. Instrumental and/or emotional feeding was found to relate to inadequate consumption of fruit, vegetables and breakfast, and positively correlated with intake of high-energy-density food. Encouragement on eating was associated with more frequent consumption of fruits, vegetables, dairy products and breakfast. Control over eating correlated with more frequent consumption of fruits, vegetables and breakfast, and less consumption of dairy products and high-energy-density food. The present study has provided evidence on the associations between parental feeding styles and dietary patterns of Hong Kong pre-school children from a reasonably large population. Parents should avoid instrumental and emotional feeding, and implement control and encouragement to promote healthy food intake. Longitudinal studies and interventions on parental feeding style are required to confirm the research findings.

Project description:Background/aimFluoride is a natural mineral present in food, water, and dental products, constituting ubiquitous long-term exposure in early childhood and across the lifespan. Experimental evidence shows fluoride-induced lipid disturbances with potential implications for cardiometabolic health. However, epidemiological studies are scarce. For the first time, we evaluated associations between repeated fluoride measures and cardiometabolic outcomes in children.MethodsWe studied ∼ 500 Mexican children from the Programming Research in Obesity, Growth, Environment and Social Stressors (PROGRESS) cohort with measurements on urinary fluoride at age 4, and dietary fluoride at ages 4, 6, and 8 years approximately. We used covariate-adjusted linear mixed-effects and linear regression models to assess fluoride associations with multiple cardiometabolic outcomes (ages 4-8): lipids (total cholesterol, HDL, LDL, and triglycerides), glucose, HbA1c, adipokines (leptin and adiponectin), body fat, and age- and sex-specific z-scores of body mass index (zBMI), waist circumference, and blood pressure.ResultsDietary fluoride intake at age 4 was associated with annual increases in triglycerides [β per-fluoride-doubling = 2.02 (95 % CI: 0.37, 3.69)], cholesterol [β = 1.46 (95 % CI: 0.52, 2.39)], HDL [β = 0.39 (95 % CI: 0.02, 0.76)], LDL [β = 0.87 (95 % CI: 0.02, 1.71)], and HbA1c [β = 0.76 (95 % CI: 0.28, 1.24)], and decreased leptin [β = -3.58 (95 % CI: -6.34, -0.75)] between the ages 4 and 8. In cross-sectional analyses at age 8, higher tertiles of fluoride exposure were associated with increases in zBMI, triglycerides, glucose, and leptin (p-tertile trend < 0.05). Stronger associations were observed in boys at year 8 and in girls prior to year 8 (p-sex interaction < 0.05). Fewer but consistent associations were observed for urinary fluoride at age 4, indicating increased annual changes in HDL and HbA1c with higher fluoride levels.ConclusionDietary fluoride exposures in early- and mid-childhood were associated with adverse cardiometabolic outcomes in school-aged children. Further research is needed to elucidate whether these associations persist at later ages.

Project description:BackgroundThe New Senior Secondary (NSS) curriculum in Hong Kong aims to change the exam-oriented culture and promote students' all-around development. This reform emphasizes student-centered learning and promotes a shift from a top-down approach to school-based management, with the ultimate goal to help students become lifelong learners. This study examined students' perceptions of the NSS curriculum with a focus on their noncognitive development (e.g., self-understanding, positive values, purpose in life, and resilience).MethodsThe data were collected from 3,498 Secondary 6 students in Hong Kong (Girls: 47.7%; Mean age: 17.33 years) using a self-reported questionnaire in 2015. We examined the psychometric properties of the instrument, "Perceptions of the New Secondary School Curriculum" (PNSC), and conducted multigroup CFA to evaluate the measurement invariance of PNSC across genders. Paired t-test analysis was used to examine whether students perceived the junior and senior secondary curricula differently. A series of multivariate analysis of variance (MANOVA) were conducted to examine students' perceptions of the curriculum by gender and by academic performance level.ResultsResults based on percentage responses showed that most students liked the curriculum and acknowledged its benefits in promoting their noncognitive development. However, substantial proportions of the students also reported relatively negative responses to some items, particularly their fondness for senior secondary education. Students generally reported higher fondness for the junior secondary curriculum than for the senior secondary curriculum. Girls had more positive perceptions of the NSS curriculum than did boys. High-performing students liked the NSS curriculum the most and perceived the most benefits of the curriculum in promoting their noncognitive skills, whereas low-performing students showed the lowest levels of fondness for/interest in the curriculum and perceived benefits.ConclusionsOur findings support previous evidence showing initial success in promoting students' noncognitive skills but also alert educators and policymakers that the curriculum should not leave the low-performing students behind. Collective efforts from schools, educational bureaus, researchers, and policymakers are needed to take appropriate measures to cater to students' balanced development.

Project description:This study aimed to initially adopt an International Healthy Eating Report Card for Preschool-Aged Children to assess the prevalence of healthy eating behaviours and favourable family home food environments (FHFEs) among preschool-aged children in Australia, Hong Kong, Singapore, and the US. We also examined which cultural contexts would exhibit significant differences in the report card scores among the four cultural contexts. In this cross-cultural study, 2059 parent-child dyads, with approximately 500 dyads in each cultural context, were recruited. The parents were asked to complete the validated International Healthy Eating Report Card Scale to assess the dimensions of the Report Card [i.e., Indicator of Children's Eating Behaviours: (1) Children's Dietary Patterns and (2) Children's Mealtime Behaviours, and Indicator of FHFEs: (3) Parental Food Choices and Preparation, (4) Home Healthier Food Availability and Accessibility and (5) Family Mealtime Environments]. Each indicator received a letter grade [i.e., A (≥80%) = excellent, B (60-79%) = good, C (40-59%) = fair, D (20-39%) = poor, F (<20%) = very poor and including the plus (+) and minus (-) signs] to represent the proportion of participants who could meet the predefined benchmarks. We also employed ANCOVA and Bonferroni's post-hoc test to examine the differences in the report card scores between the four cultural contexts. A significance level was set at p < 0.05. The average overall report card grade across the four cultural contexts was "B-" (Good), ranging from "C+" (Singapore and the US) to "B-" (Australia and Hong Kong). The average grade for Children's Eating Behaviours was classified as Fair ("C-"), while the average grade for FHFEs was classified as Good ("B+") for all cultural contexts. A comparison of the overall report card scores revealed that Australia exhibited a significantly higher report card score than Singapore and the US, while Hong Kong achieved a significantly higher score than Singapore. The International Healthy Eating Report Card provided an overview of the prevalence of healthy eating in different cultural contexts. We believe that the International Healthy Eating Report Card may offer new perspectives on interventions for fostering healthy eating in young children.
