Diet quality and eating behavioural patterns in preschool children in Hong Kong.

BACKGROUND AND OBJECTIVES: To assess the diet quality and eating behaviour of preschool children, investigate parents' feeding practices, and obtain information on the kindergarten nutrition environment of Hong Kong children aged 30-60 months. METHODS AND STUDY DESIGN: Dietary information was obtained using multiple 24-hour recalls. Questionnaires were developed to obtain information on children' seating behaviour, parents' feeding practices and preschool nutrition environment. RESULTS: A total of 302 children and 23 local kindergartens from three regions of Hong Kong were surveyed. The results showed consumption of vegetable and fruit were adequate; however, consumption of grain and meat were excessive, while milk and dairy intakes were inadequate. On average, the children consumed 1,280 kcal per day, or 92% of the Chinese Nutrition Society's energy recommendation. For macronutrients, the mean percentages of energy from carbohydrate, protein and fat were 55%, 17% and 28%, respectively, which are within the United States Acceptable Macronutrient Distribution Ranges. The mean intakes of carbohydrate and protein were 175 g and 53.4 g, respectively. For micronutrients, the mean intakes of vitamin D, calcium, iron and zinc were significantly lower than the reference nutrient intake or adequate intake (p<0.05), but those of sodium and niacin were significantly higher than the tolerable upper intake levels (p<0.05). CONCLUSION: This study showed that diet quality among children in Hong Kong needs to be improved, as some nutrients are consumed in excess whereas others are consumed in inadequate amounts. Other results on children's eating behaviour, parent's feeding practices and school nutrition environment are also reported.

Socioeconomic disparity in breast cancer detection in Hong Kong--a high income city: retrospective epidemiological study using the Breast Cancer Registry.

BACKGROUND: It is not known whether socioeconomic disparities affect the detection of breast cancer in Asian countries where the incidence of breast cancer is a rising trend. In this study, we explore the socioeconomic profiles of women and the stage of the disease at the time of diagnosis in breast cancer patients aged 40 or over in Hong Kong. METHOD: During the period 2008 to 2011, 5393 breast cancer patients registered with the Hong Kong Breast Cancer Registry. Participants and their clinicians were asked to complete standardised questionnaires including patient socio-demographics, health history and risk factors, the course of the disease, post-treatment physical discomfort and psychosocial impact, follow-up recurrence and survival status. RESULTS: Monthly household incomes, educational levels and the practice of regular screening are independently associated with the stage of the disease at diagnosis. Higher socioeconomic status and a higher educational level were associated with an earlier stage of the disease at the time of diagnosis. Yearly clinical examinations, ultrasound and mammographic screening every 2 to 3 years were significantly associated with the earlier detection of breast cancer. CONCLUSION: There were socioeconomic disparities among Hong Kong women who were found to have breast cancer. Population-based screening policies, including raising awareness among women at risk, should be implemented.

Risk factors and natural history of breast cancer in younger Chinese women.

AIM: To investigate the age differences in the risk factors, clinicopathological characteristics and patterns of treatment of female breast cancer patients. METHODS: Seven thousand one hundred and fifty-two women with primary breast cancer from the Hong Kong Breast Cancer Registry were recruited after receiving patients' consent, they were asked to complete standardized questionnaires which captured their sociodemographic characteristics and risk factors associated with breast cancer development. Among them, clinicopathological data and patterns of treatment were further collected from medical records of 5523 patients with invasive breast cancers. Patients were divided into two groups according to the age at diagnosis: younger (< 40 years old) vs older patients (≥ 40 years old) for subsequent analyses. RESULTS: Analysis on the sociodemographic characteristics and exposure to risk factors were performed on 7152 women with primary breast cancer and the results revealed that younger patients were more likely to have unhealthy lifestyles; these include a lack of exercise (85.4% vs 73.2%, P < 0.001), having high stress in life (46.1% vs 35.5%, P < 0.001), having dairy/meat-rich diets (20.2% vs 12.9%, P < 0.001), having alcohol drinking habit (7.7% vs 5.2%, P = 0.002). Younger patients were also more likely to have hormone-related risk factors including nulliparity (43.3% vs 17.8%, P < 0.001) and an early age at menarche (20.7% vs 13.2%, P < 0.001). Analyses on clinicopathological characteristics and patterns of treatment were performed on 5523 women diagnosed with invasive breast cancer. The invasive tumours in younger patients showed more aggressive pathological features such as having a higher percentage of grade 3 histology (45.7% vs 36.5%, P < 0.001), having a higher proportion of tumours with lymphovascular invasion (39.6% vs 33.2%, P = 0.003), and having multifocal disease (15.7% vs 10.3%, P < 0.001); they received different patterns of treatment than their older counterparts. CONCLUSION: Younger patients in Hong Kong are more likely to encounter risk factors associated with breast cancer development and have more aggressive tumours than their older counterparts.
