Food exports and imports of New Zealand in relation to the food-based dietary guidelines.

Background/objectives: It has not been reported that previously how much food New Zealand (NZ), population 4.9 million (M), exports and imports in terms of how many people this food would feed if the food-based dietary guidelines (FBDG) were followed. In New Zealand, 40% of adults and 20% of children live in a household with severe to moderate food insecurity.

Pacific Islands Families Study: Physical growth to age 14 and metabolic risk.

Background: The relationships between the trajectories of weight gain from early childhood to adolescence and risk for metabolic disease are not well understood.

Objective: The objective of the study is to examine the relationships between weight gain from 2 to 14 years and metabolic risk factors at age 14 years in Pacific Island children.

Methods: z scores for weight were calculated at each of the ages 2.

Secular trends 2013-2017 in overweight and visible dental decay in New Zealand preschool children: influence of ethnicity, deprivation and the Under-5-Energize nutrition and physical activity programme.

Early-life intervention to reduce obesity and poor dental health through early-life nutrition will improve health outcomes in later life. This study examined the prevalence of overweight and obesity and visual dental decay in 4-year old children in New Zealand between 2013 and 2017, and the impact of a nutrition and physical activity intervention programme, Under-5-Energize (U5E), on prevalence of these conditions within ethnic groups and by deprivation. The data set included 277,963 4-year-old children, including 25,140 from the Waikato region children of whom 8067 attended one of the 121 early childhood centres (ECC) receiving the U5E programme from 2014.

Under 5 Energize: Tracking Progress of a Preschool Nutrition and Physical Activity Programme with Regional Measures of Body Size and Dental Health at Age of Four Years.

To reduce weight gain and encourage healthy eating including reduced sugar intake, Under 5 Energize (U5E) was introduced to 121 early-childhood-centres in the Waikato region of New Zealand in July 2013. Using anonymized data collected from January 2013 to September 2016 through free physical assessments of all 4-year-olds provided by the NZ Ministry of Health, the prevalence of obesity and dental decay children measured in the Waikato region was examined. Data were divided into four periods representing pre-implementation and 3 years of gradual implementation.

Metabolic disruption identified in the Huntington's disease transgenic sheep model.

Huntington's disease (HD) is a dominantly inherited, progressive neurodegenerative disorder caused by a CAG repeat expansion within exon 1 of HTT, encoding huntingtin. There are no therapies that can delay the progression of this devastating disease. One feature of HD that may play a critical role in its pathogenesis is metabolic disruption.

A triad of highly divergent polymeric immunoglobulin receptor (PIGR) haplotypes with major effect on IgA concentration in bovine milk.

The aim of this study was to determine a genetic basis for IgA concentration in milk of Bos taurus. We used a Holstein-Friesian x Jersey F2 crossbred pedigree to undertake a genome-wide search for QTL influencing IgA concentration and yield in colostrum and milk. We identified a single genome-wide significant QTL on chromosome 16, maximising at 4.

Food frequency information--relationships to body composition and apparent growth in 4-year-old children in the Pacific Island Family Study.

Aims: To record at the 4-year measurement point for the Pacific Island Family Study the most frequently eaten foods and to identify associations with growth and body composition.

Methods: A food frequency questionnaire relating to consumption of 111 foods over a 4 week period was administered to the 739 children, to be completed by a parent. Body composition of the children was measured by anthropometry and body fatness by bioimpedance analysis.

Are energy drinks contributing to the obesity epidemic?

The consumption of energy drinks containing sucrose and caffeine is increasing worldwide. Ten healthy women aged 18 to 22 years and fasted overnight were randomly allocated to a standardised dose of sucrose either as an "energy" drink (containing sucrose and caffeine) or lemonade on the first day and then crossed over to the alternative drink on a second day. For thirty minutes before and thirty minutes after drinking oxygen consumption and carbon dioxide production were measured in the resting subject breath-by-breath by indirect calorimetry and the rates of carbohydrate and fat oxidation calculated.
