Vitamin D-fortified milk achieves the targeted serum 25-hydroxyvitamin D concentration without affecting that of parathyroid hormone in New Zealand toddlers

For young children, the level of vitamin D required to ensure that most achieve targeted serum 25-hydroxyvitamin D [25(OH)D] ≥50 nmol/L has not been studied. We aimed to investigate the effect of vitamin D-fortified milk on serum 25(OH)D and parathyroid hormone (PTH) concentrations and to examine the dose–response relationship between vitamin D intake from study milks and serum 25(OH)D concentrations in healthy toddlers aged 12–20 mo living in Dunedin, New Zealand (latitude 46°S). Data from a 20-wk, partially blinded, randomized trial that investigated the effect of providing red meat or fortified toddler milk on the iron, zinc, iodine, and vitamin D status in young New Zealand children (n = 181; mean age 17 mo) were used. Adherence to the intervention was assessed by 7-d weighed diaries at wk 2, 7, 11, 15, and 19. Serum 25(OH)D concentration was measured at baseline and wk 20. Mean vitamin D intake provided by fortified milk was 3.7 μg/d (range, 0–10.4 μg/d). After 20 wk, serum 25(OH)D concentrations but not PTH were significantly different in the milk groups. The prevalence of having a serum 25(OH)D <50 nmol/L remained relatively unchanged at 43% in the meat group, whereas it significantly decreased to between 11 and 15% in those consuming fortified study milk. In New Zealand, vitamin D intake in young children is minimal. Our findings indicate that habitual consumption of vitamin D-fortified milk providing a mean intake of nearly 4 μg/d was effective in achieving adequate year-round serum 25(OH)D for most children.

Quantities of foods consumed by 12- to 24-month-old New Zealand children

Aim:  The present study aimed to estimate small, median and large daily quantities of frequently consumed foods and identify which food groups are important sources of key micronutrients for 12- to 24-month-old New Zealand children.

Methods:  A community-based cross-sectional survey was conducted in three cities in the South Island of New Zealand. Healthy toddlers (n = 188) were randomly selected using multistage sampling. Three non-consecutive 1-day weighed food records were collected from each child and the frequencies and daily quantities of foods and beverages, and important sources of iron and zinc, were determined.

Results:  Fifty percent or more of the children consumed the following foods at least once over 3 days (median gram intake among toddlers who consumed the food): milk (366 g), white bread (29 g), banana (70 g), potato (34 g), cheese (12 g), apple (39 g), ‘Weetbix’ whole-wheat breakfast cereal (16 g), yeast extract spread (‘Marmite’, ‘Vegemite’) (2 g), carrot (17 g) and margarine (4 g). Dairy, cereals and the meat/fish/poultry/eggs/nuts food group were the most important sources of iron and zinc in the toddlers' diets, providing 69.1% of iron and 86.3% of zinc.

Conclusion:  This research provides dietitians, other health professionals, researchers and policy-makers with detailed information on daily quantities of foods and beverages frequently consumed by toddlers that can be used for dietetic counselling, dietary assessment, and to develop food-based dietary guidelines specifically for toddlers.

The settlement and social inclusion of immigrant youth in New Zealand

The immigrant population of Aotearoa New Zealand has increased significantly over recent years. This rise in ethnic minority populations, especially from non-English speaking countries, has significant social implications for the country. Anecdotal and empirical evidence in New Zealand show that many immigrant youth are not socially included, and that this compromises their ability to settle successfully in New Zealand. This study investigates the settlement and social inclusion of immigrant youth in New Zealand. It investigates the significant/actors that act as barriers to their settlement and social inclusion. The study gathers data through face to face and telephone interviews from key informants who are service providers and experts in six cities in New Zealand. Data is analysed using an inductive approach to produce primarily qualitative data which identifies key themes and issues for different age groups, genders, migrant and refugee groups. It supplements this data with some quantitative data on frequency, duration and intensity. Findings reveal that most immigrant youth generally do not feel well settled and socially included in New Zealand, and that some may suffer psychological and social consequences due to this.

Vitamin D and health in adults in Australia and New Zealand : a position statement

The prevalence of vitamin D deficiency varies, with the groups at greatest risk including housebound, community-dwelling older and/or disabled people, those in residential care, dark-skinned people (particularly those modestly dressed), and other people who regularly avoid sun exposure or work indoors.

Most adults are unlikely to obtain more than 5%–10% of their vitamin D requirement from dietary sources. The main source of vitamin D for people residing in Australia and New Zealand is exposure to sunlight.

A serum 25-hydroxyvitamin D (25-OHD) level of ≥ 50 nmol/L at the end of winter (10–20 nmol/L higher at the end of summer, to allow for seasonal decrease) is required for optimal musculoskeletal health.

Although it is likely that higher serum 25-OHD levels play a role in the prevention of some disease states, there is insufficient evidence from randomised controlled trials to recommend higher targets.

For moderately fair-skinned people, a walk with arms exposed for 6–7 minutes mid morning or mid afternoon in summer, and with as much bare skin exposed as feasible for 7–40 minutes (depending on latitude) at noon in winter, on most days, is likely to be helpful in maintaining adequate vitamin D levels in the body.

When sun exposure is minimal, vitamin D intake from dietary sources and supplementation of at least 600 IU (15 μg) per day for people aged ≤ 70 years and 800 IU (20 μg) per day for those aged > 70 years is recommended. People in high-risk groups may require higher doses.

There is good evidence that vitamin D plus calcium supplementation effectively reduces fractures and falls in older men and women.

The New Zealand gaming and betting survey : Chinese and Indian people's experience

Purpose – The purpose of this paper is to analyse attitudes, understanding of gambling and gambling related harm among Asians in New Zealand using secondary data from the New Zealand 2006/07 Gaming and Betting Attitudes Survey (GBAS).

Design/methodology/approach – This survey interviewed 1,973 nationwide randomly selected youths and adults (=18 years) using structured questionnaire. Chinese (N=113) and Indian (N=122) data were analysed separately to compare between them and with NZ Europeans (N=792). Descriptive analysis was carried out and was subsequently tested for significant correlations by weighted (p<0.01) and un-weighted (p<0.05) variables.

Findings – A higher proportion of Chinese males (66.8 percent) represented in the survey compared to Indian (43.0 percent) and NZ European (48.9 percent) where Chinese consisted of more youthful age structure. Chinese respondents were more likely to be in the lowest income bracket (NZ$10,000) compared to others. Among the ten gambling activities “casino table gambling” and “casino electronic machines” (slot-style machine) were most popular among the Chinese where Indians preferred “gambling/casino evening”. A significant proportion of Chinese were unwilling to refer family or friends to gambling help services despite believing that gambling does more harm than good. Pre-committed gambling sum was the most common harm minimising strategy suggested by participants. They believed education and consultation could deter youths from harmful gambling.

Research limitations/implications – This survey highlighted gambling behaviours and thoughts of the ethnic minority population in New Zealand. Study outcomes would be valuable in formulating ethnic specific preventative programme and may have policy implication.

Originality/value – There has been limited research on gambling behaviour of ethnic minorities in New Zealand. This paper fills some of the gaps.

The impact of climate variability and change on cryptosporidiosis and giardiasis rates in New Zealand

Aim: To investigate the spatial relationship between climate variability and cryptosporidiosis and giardiasis notifications in New Zealand between 1997 and 2006.

Methods: Negative binomial regression was used to analyse spatial relationships between cryptosporidiosis and giardiasis notifications in New Zealand between 1997 and 2006, and climatological average rainfall and temperature at the Census Area Unit (CAU) level. The quality of domestic water supplies, urban-rural status and deprivation were included as covariates.

Main results: Giardiasis: There was a positive association between rainfall and giardiasis and between temperature and giardiasis.

Cryptosporidiosis: There was a positive association between rainfall and cryptosporidiosis and a negative association between temperature and cryptosporidiosis. The effect of rainfall was modified by the quality of the domestic water supply.

Conclusions: These findings suggest that climate variability affects protozoan disease rates in New Zealand. However, predicting the effect of climate change from this study is difficult, as these results suggest that the projected increases in temperature and rainfall may have opposing effects on cryptosporidiosis rates. Nevertheless, water supply quality appeared to modify the impact of increased rainfall on cryptosporidiosis rates. This finding suggests that improving water supply quality in New Zealand could reduce vulnerability to the impact of climate change on protozoan diseases.

Do service and merchandise exporters behave and perform differently? : a New Zealand investigation

Research on export behaviour and the determinants of export performance of manufacturing firms abounds in the literature. By contrast relatively little research has been undertaken that focuses on service exporters despite the growing importance of service exports in most advanced industrialised countries. This paper compares the export behaviour and performance of service firms to those of manufacturing firms. The study is based on a survey of 155 small and medium size exporters from New Zealand. The results suggest that service exporters are distinctively unique in many respects and exhibit export behaviours that are different from exporters of merchandise. Generally, service firms have greater flexibility to adapt their products to the specific requirements of their customers, use direct export channels more often and are also more proactive than merchandise firms in the establishment of future export strategies. Overall, the size and commitment of service exporters have the greatest influence on their performance.

Cinema of Australia and New Zealand

From The Story of the Kelly Gang in 1906 to the Lord of the Rings trilogy, Australia and New Zealand have made a unique impact on international cinema. This book celebrates the commercially successful narrative feature films produced by these film cultures as well as key documentaries, shorts and independent films. This coverage also invokes issues involving national identity, race, history and the ability of two small film cultures to survive the economic and cultural threat from Hollywood. Chapters on well-known films, and directors, such as The Year of Living Dangerously (Peter Weir, 1982), The Piano (Jane Campion, 1993), Fellowship of the Ring (Peter Jackson, 2001) and Rabbit Proof Fence (Philip Noyce, 2002) are included with less celebrated, but equally important, films and filmmakers such as Jedda (Charles Chauvel, 1955), They're a Weird Mob (Michael Powell, 1966), Vigil (Vincent Ward, 1984) and The Goddess of 1967 (Clara Law, 2000)

Insuring for a crisis: deposit insurance and the GFC, the Australian and New Zealand experience

Deposit insurance schemes were an important element in policy responses to the global financial crisis (GFC). There has been considerable debate about the nature and efficacy of such policy measures in alleviating the fallout from financial crises. The GFC highlighted problems associated with deposit insurance schemes including moral hazard, coverage limits, co-insurance, cross border issues and market distortions. Despite these shortcomings, deposit insurance schemes were able to ameliorate the financial panic experienced and reduce contagion. This paper evaluates the Australian and New Zealand experience with deposit insurance introduced in response to the GFC, and compares this to the OECD experience. It reflects on the performance of deposit insurance schemes considered against the attributes of good policy design, and evaluates the specific problems and strengths encountered during the GFC.
