Interaction between XRCC1 Polymorphisms and Intake of Long-Term Stored Rice in the Risk of Esophageal Squamous Cell Carcinoma:A Case-Control Study

Objective This study aimed to explore the roles of three common single nucleotide polymorphisms in the X-ray repair cross-complementing group-1 gene （XRCC1） and of life style factors and their possible interactions in the risk of esophageal squamous cell carcinoma （ESCC） in China. Methods A population-based case-control study of 432 cases and 915 controls was conducted in Yangzhong County, Jiangsu Province, China. Subjects were interviewed by trained interviewers using a structured questionnaire that included questions on demographics and life style. XRCC1 genotypes were analyzed using a polymerase chain reaction based restriction fragment length polymorphism （PCR-RFLP） assay. Unconditional logistic regression analysis was used to calculate adjusted odds ratios （aORs） and 95% confidence intervals （CIs） for associations of ESCC with XRCCI polymorphisms and lifestyle-related factors. Results Both the drinking of river water and alcohol intake history were significantly associated with an increased risk of ESCC among men with aORs of 4.20 （95% Ch 2.90-6.07） and 2.03 （95% Ch 1.43-2.89）, respectively. For women, the corresponding odds ratios were 8.37 （95% CI： 5.09-13.75） for river water drinking and 12.78 （95% CI： 2.69-60.69） for long-term stored rice intake. After the XRCC1 G28152A polymorphism was adjusted for potential confounders, subjects with GA and AA genotypes had an increased risk for ESCC （aOR： 1.21, 95% CI： 0.93-1.56）, compared with subjects with a GG genotype, and a positive multiplicative interaction between intake of long-term stored rice and the XRCC1 G28152A polymorphism was observed （P=O.009）.Conclusions Our findings suggest that both lifestyle-related factors, including drinking river water, long-term stored rice and alcohol intake, and the XRCC1 G28152A polymorphism were possible risk factors for ESCC, and that the XRCC1 G28152A polymorphism modified the effect of long-term stored rice intake on the risk of ESCC among Chinese people.

Comparison of Public Health Nurse’s Lifestyle Counseling Skills for Clients with Different Readiness of Behavior Changes in Primary Care Settings

Purpose: Public health nurses (PHNs) are required to assess the readiness of the clients and provide lifestyle counseling accordingly. The purpose of this study was to compare the lifestyle counseling provided for clients with different levels of readiness based on self-evaluations and independent assessment. Methods: Participants were PHNs with 10 years’ experience or less. Lifestyle counseling skills were measured through a simulated counseling session in a primary setting lasting up to 30 minutes, followed by a review session, where the participant provided self-evaluations, and the simulated client provided others-evaluations, of the session. The simulated clients played the role of clients at either the pre-contemplation or contemplation stage of preparedness as per the stages of behavior change theory. Results: The self-evaluation results showed that the mean scores for five of the six skill categories, are lower in the precontemplation-stage client cases than in the contemplation-stage client cases, and significantly so for two skill categories. The others-evaluations showed significantly lower mean scores for all skill categories in the precontemplation cases than in the contemplation cases. Conclusion: The PHNs and simulated clients agreed that lifestyle counseling skills were inadequate for the precontemplation cases, as compared with the contemplation cases. The lifestyle counseling skills of PHNs with less experience may not be well-adjusted to the readiness of the client, indicating difficulties in supporting less prepared clients.

Factors Affecting Children’s Cholesterol Levels with a View to Prevent Cardiovascular Disease—The Unique Benefits of Health Screening at the Elementary School

Background: The prevention of cardiovascular disease (CVD) can substantially contribute to reducing the mortality rate across countries. The level of interest in cholesterol among experts increases when the subjects are elderly and obese individuals. However, specialists do not recommend that children should receive the cholesterol test. The objective of this study was to investigate the distribution of cholesterol levels among the children of public school and their parents’ lifestyles that are associated with cholesterol levels, and to assess the need for and utility of cholesterol testing in school settings. Methods: The study investigated a group of 226 fourth-grade public school children aged between 9 and 10 years and guardians in Akitakatacity of Hiroshima Prefecture, Japan. Multiple regression analyses were performed with the logarithmic value of cholesterol levels as a response variable, awareness about lifestyles and health of children as an explanatory variable, and child’s sex and body mass index (BMI) as moderating variables. Using questionnaires about lifestyles, the step-down procedure was applied in multiple regression analyses to narrow down relevant lifestyle variables. Results: The percentage of children with the high total cholesterol (TC) value was about 15 and with low-density lipoprotein (LDL) cholesterol value was about 10. Children with low high-density lipoprotein (HDL) cholesterol value were 5%. Treatment was not required according to the comprehensive assessment. Cholesterol levels were associated with the situation of the children and their guardians as follows, guardian need to consider the food, and child has the correct knowledge about food like how to eat snacks. Conclusions: Children had poor cholesterol levels. From childhood, along with the parents, there is a need to learn about appropriate level of cholesterol for CVD prevention.

Dietary behaviour changes to improve nutritional quality and health outcomes

This narrative review examines the changes required in dietary behaviours to address the current global burden of disease resulting from diet-associated cardiometabolic dysfunction. Beginning with known relationships between nutritional factors and health outcomes, the review identifies a number of problems with current dietary behaviours, using examples from the Australian context. Implications for practice are then discussed drawing on insights from research in dietary trials. From a concerted research effort across the globe, the effects of foods, food components and dietary patterns on cardiometabolic parameters have been reasonably well exposed. The evidence base for these effects underpins dietary guidelines, which aim to meet nutritional re-quirements and protect against cardiometabolic disease. Thus foods recommended in dietary guidelines tend to be consistent with research that identifies foods that appear protective and those that appear detrimental to health. The need for dietary behaviour change is apparent through analyses that have exposed increasing consumption of detrimental foods, despite the availability of healthy foods. However, behaviour change is a complex area, and where weight loss is also required, there is high level evidence that interdisciplinary efforts combining diet, physical activity and psychological support are warranted. Insights from dietary trials and research indicate that focussing on foods and dietary patterns is integral to the specific dietary change required for health outcomes, but social and behavioural factors will influence the achievement of these changes.
