Background and Objectives: The Tick programme of the National Heart Foundation (NHF) is the longest standing voluntary front of pack signpost nutrition logo in New Zealand. It provides a platform for collaboration with the food industry to encourage development of healthier products. This study evaluated the impact of the Tick programme on sodium in processed food. Methods and Study Design: Fifty-two Tick programme products from food categories known to contribute substantially to sodium intake were identified. Sales volumes (kg) from January 2011 to December 2013 were multiplied by changes in sodium content over that time, producing an estimate of programme impact. Five semi-structured interviews with industry representatives were conducted, to look at other influences for sodium reduction, and themes identified through methods of thematic analysis. Results: Over the period, the Tick programme influenced food companies to remove approximately 16 tonnes of salt through the reformulation and formulation of 52 Tick-approved breakfast cereals, edible oil spreads, cooking sauces and processed poultry products. Other factors influencing sodium reduction reported by company representatives included increased consumer and industry interest in healthier product nutrition profiles and other sodium reduction programmes targeting reformulation/formulation. Conclusions: The Tick remains a credible and well-recognized brand and may provide a competitive edge for participating food manufacturers in the current market. The Tick programme is effective in influencing industry to reduce sodium in processed foods in New Zealand. The combined impact of the Tick and other NHF programmes has the potential to reduce population sodium intake and improve health outcomes.

Background and Objectives: With prevalence of childhood obesity increasing rapidly, developing of effective and sustainable intervention strategies is becoming more and more important for the prevention of childhood obesity in China. A trial was developed to evaluate the effect of comprehensive school-based intervention on childhood obesity. Methods and Study Design: A multi-center cluster randomized controlled trial was conducted among urban children (n=9,867) aged 6-13 years in 38 primary schools from six large cities. Comprehensive intervention, nutrition education and physical activity interventions were carried out among children. Nutrition education was also targeted towards teachers, parents and health workers in intervention schools. The program was implemented for 2 semesters from May 2009 to May 2010. Results: The combined prevalence of overweight and obesity increased by 1.5 percent (22.7% vs 24.2%, p＜0.001) in control group while 0.2 percent in comprehensive intervention group (23.6% vs 23.8%, p=0.954) after intervention (p=0.067). The effect was significantly stronger among girls than boys (-1.4% vs -0.9%, p=0.028). A significant intervention effect was found on BMI for -0.3 kg/m^2 (95% confidence interval (CI): -0.4, -0.2; p＜0.001), BMI z scores for -0.14 (95% CI: -0.18, -0.11; p＜0.001)，body fat for -0.8 percent (95% CI: -0.9, -0.6; p＜0.001), waist circumference for -0.5 cm (95% CI: -0.6, -0.3; p＜0.001), blood serum glucose for -0.20 mmol/L (95% CI: -0.24, -0.16; p＜0.001) and cholesterol for -0.32 mmol/L (95% CI: -0.34, -0.30; p＜0.001). Conclusions: We observed moderately significant effects on combined prevalence of overweight and obesity, BMI, BMI z scores, waist circumference, percentage body fat, glucose and lipid for a comprehensive school-based intervention of childhood obesity in China.

Background and Objectives: The few studies that have assessed the association between rice intake and mortality have generated inconsistent results. We assessed whether rice intake was associated with cardiovascular disease (CVD) mortality, cancer mortality and all-cause mortality in a prospective cohort of the Chinese population. Methods and Study Design: We prospectively studied 2,832 adults aged 20 years and above with a mean follow up of 10 years. Rice intake was measured by a 3-day weighed food record (WFR) in 2002. Hazard ratios (HRs) and 95% CI were calculated by competing risks regression (CVD and cancer mortality) and Cox proportional hazards analysis (all-cause mortality). Results: We documented 184 deaths (including 70 CVD deaths and 63 cancer deaths) during 27,742 person-years of follow-up. No association between rice intake and all-cause mortality was found. After adjusting for sociodemographic and lifestyle factors as well as energy and fat intake, HRs for CVD mortality across tertiles of rice intake were 1.00,0.47 (95% CI 0.25-0.87), and 0.49 (95% CI 0.21-1.13) (p for trend 0.049). Conclusions: There was no association between rice intake and all-cause mortality.

Background and Objectives: Emerging evidence suggests potential effects of nutrients/foods on sleep parameters. However, no studies have addressed the complex interactions among nutrients/foods and relate them to sleep outcomes. To investigate the associations between dietary patterns and sleep parameters (polysomnography (PSG) measured and self-reported sleep symptoms) in a large sample of community dwelling men in South Australia. Methods and Study Design: Cross-sectional analysis was conducted of participants in the Men Androgen Inflammation Lifestyle Environment and Stress cohort enrolled in a sleep sub-study (n=784, age 35-80 years). Dietary intake was measured by a validated food frequency questionnaire. Dietary patterns were identified by factor analysis. Sleep was assessed by an overnight home PSG and self-reported questionnaires. Results: Two factors were obtained by factor analysis: Factor 1 was characterised by high intakes of vegetables, fruits, and legumes and factor 2 was characterised by processed meat, snacks, red meat and take-away foods. Three categories of the dietary patterns were defined (prudent, mixed and western) through classification of the sample according to the actual consumption higher or lower of each factor. The prudent (factor 1 dominant) and mixed dietary patterns were inversely associated with sleep onset, compared with the western dietary pattern (factor 2 dominant) (β=-6.34 (95% CI-1.11, -11.57), β=-4.34 (95% CI-8.34, -0.34) respectively)). The association was only significant with the prudent dietary pattern after multiple comparison adjustment. No associations were found with between dietary patterns and other sleep outcomes. Conclusions: The prudent dietary pattern was associated with a faster sleep onset, which may provide a solution for sleep management.

Background and Objectives: Associations between genetic variants in the hepcidin regulation pathway and iron status have been reported in previous studies. Most of these studies were conducted in populations of European descent and relatively few studies have been conducted in Chinese populations. In this study, we evaluated associations between single-nucleotide polymorphisms (SNPs) in the hepcidin regulation pathway, serum ferritin (SF) and soluble transferrin receptor (sTfR) in Chinese adolescents. Methods and Study Design: In total, 692 students from rural boarding schools were selected from six cities in China. The participants were divided into case and control groups according to criteria for SF and sTfR. Furthermore, 33 SNPs in TMPRSS6, TF, TFR2, BMP2, BMP4, HJV, CYBRD1, HFE, IL6, PCSK7, HAMP, KIAA1468, and SRPRB were selected. Associations between the genetic variants and SF or sTfR were detected. Results: For SF, rs4820268 in TMPRSS6 was associated with an SF ＜25 ng/mL status. Carriers of the G/G genotype of rs4820268 exhibited significantly lower SF levels than A allele carriers did (p=0.047). For sTfR, rs1880669 in TF, rs4901474 in BMP4, and rs7536827 in HJV were significantly associated with an sTfR ≥4.4 mg/L status. However, in general linear model analysis, after adjustment for age, sex, and location, only rs1880669 exhibited a stable association with higher sTfR levels (p=0.032). Conclusions: We found rs4820268, in TMPRSS6 that was associated with a low SF level, as previously reported, and a new association between 1880669 in TF and sTfR.
