Aim: In New Zealand, there are few adequate food frequency questionnaires for assessing dietary intake. This study aimed to develop and assess the relative validity of a multi‐nutrient, culturally appropriate, semi‐quantitative food frequency questionnaire for use in young adult New Zealand women (the New Zealand Women's Food Frequency Questionnaire (NZWFFQ)). Methods: Women (n = 110) aged 16–45 years of Māori, Pacific or European ethnicity completed a NZWFFQ assessing dietary intake over the previous month, and a 4‐day weighed food record. Relative validity was evaluated by comparing nutrient intakes from the NZWFFQ with the food record using Spearman's rank correlation coefficients, cross‐classification, the weighted kappa statistic and Bland–Altman analysis. Results: Nutrient intake was higher from the NZWFFQ compared with the food record for all nutrients (range: 1%–64% difference) except alcohol (−16% difference). Energy‐adjusted correlations ranged from 0.23 to 0.67 (average 0.48). Correct classification into same and adjacent quartiles was over 70% for all nutrients except folate and vitamin D. Gross misclassification into opposite quartiles ranged from 1% (monounsaturated fat, magnesium, calcium) to 10% (iron). The weighted kappa showed poor agreement for vitamin D and folate, fair agreement for most nutrients, and moderate agreement for fibre, vitamin E, magnesium, calcium and phosphorus. Conclusions: The NZWFFQ overestimated intake of nearly all nutrients. While not suitable for assessing absolute intake, the NZWFFQ is suitable for ranking individuals based on nutrient intake demonstrating reasonable relative validity for this purpose.

Aim: Total gastrectomy and Ivor Lewis oesophagectomy procedures are the mainstay of upper gastrointestinal cancer management. Maintenance of adequate nutritional intake is essential for positive patient outcomes. Although numerous nutritional support options exist, clear evidence‐based guidelines on the optimal means and duration of nutritional support are lacking. The aim of this study is to establish preliminary data on the current perioperative nutritional practices of upper gastrointestinal surgeons performing these procedures across Australia and New Zealand. It is hoped this will help provide the platform for future research towards establishing evidence‐based guidelines in upper gastrointestinal surgery. Methods: A questionnaire exploring the nutritional practices and considerations of surgeons was developed and emailed to the members of the Australia & New Zealand Gastric & Oesophageal Surgery Association. Results: A total of 27.4% of Australia & New Zealand Gastric & Oesophageal Surgery Association members completed the questionnaire. Surgeons reported inserting a jejunostomy feeding tube intraoperatively in Ivor Lewis oesophagectomy procedures 80–100% of the time, compared to only 20–39% of the time in total gastrectomy procedures. For both procedures, surgeons often refer their patients to a dietitian preoperatively, and always postoperatively. Preoperative immune‐enhancing nutrition is rarely administered. Patient age and BMI are deemed to be of low importance when determining the means of nutritional support. Conclusions: This study has demonstrated the current nutritional practices employed in Australia and New Zealand for patients undergoing major upper gastrointestinal surgery. Questions remain regarding the noted differences between procedures as well as the optimal means and duration of perioperative nutritional support. [ABSTRACT FROM AUTHOR]

Aim: Fruit and vegetables are strongly promoted because of the nutrients they provide; many processed products contain added sugar and sodium. The present study aims to quantify the sugar and sodium content of pre‐packaged fruit and vegetable‐based products that are available in New Zealand supermarkets. Methods: Nutrition Information Panel data were collected from non‐frozen, processed fruit and vegetable products in New Zealand supermarkets (including soups, sauces, jams and spreads, pickles, chutneys and dips, and canned/bottled fruit and vegetables) where fruit and/or vegetables were the majority ingredient(s). Results: With the exception of canned/bottled vegetables, more than 60% of products contained added sugar. Per serve, the median sugar content was highest in canned/bottled fruit (17.8 g). More than 75% of soups, vegetable‐based sauces, pickles/chutneys and canned/bottled vegetables contained added sodium, with soups (722 mg) recording the highest median values per serve. Conclusions: Consumers need to be aware that although they are encouraged to eat a diet high in fruit and vegetables, there may be large quantities of added sugar and sodium in manufactured fruit and vegetable products that can have significant negative impacts on their health. Government health promotion campaigns encouraging the consumption of fruit and vegetables should be careful to target fresh, frozen and home‐prepared foods, and work on educating the public about the lower nutritional quality associated with most processed fruit and vegetable products.

Aim: To establish the prevalence of nutrition risk and associated risk factors among adults of advanced age newly admitted to hospital. Methods: A cross‐sectional study was undertaken in adults aged over 85 years admitted to one of two hospital wards in Auckland within the previous 5 days. An interviewer‐administered questionnaire was used to establish participant's socio‐demographic and health characteristics. Markers of body composition and muscle strength were collected. Nutrition risk was assessed using the Mini Nutritional Assessment‐Short Form (MNA‐SF), dysphagia risk using the 10‐Item Eating Assessment Tool (EAT‐10) and level of cognition using the Montreal Cognitive Assessment. Results: A total of 88 participants with a mean age of 90.0 ± 3.7 years completed the assessments. A third (28.4%) of the participants were categorised by the MNA‐SF as malnourished and 43.2% were classified at risk of malnutrition. A third (29.5%) were at risk of dysphagia as assessed by EAT‐10. Malnourished participants were more likely to be at risk of dysphagia (P = 0.015). The MNA‐SF score was positively correlated with body mass index (r = 0.484, P < 0.001) and grip strength (r = 0.250, P = 0.026) and negatively correlated with risk of dysphagia (r = −0.383, P < 0.001). Conclusions: Among newly hospitalised adults of advanced age, over two thirds were malnourished or at risk of malnutrition, and a third were at risk of dysphagia. Nutrition risk was positively correlated with low BMI and grip strength and negatively correlated with dysphagia risk. Findings highlight the importance of screening for dysphagia risk, especially in those identified to be malnourished or at nutrition risk. [ABSTRACT FROM AUTHOR]

Aim To investigate the potential of the Food Standards Australia New Zealand nutrient profiling criterion to underpin restrictions on the advertising of 'unhealthy' foods to children by comparing it to other established criteria. Methods Two weeks of food advertising from 6:00 a.m. to 9:00 p.m. on three Sydney television channels was categorised as passing or failing the nutrient profiling criteria. Nutrition information on energy, saturated fat, sodium, sugar, protein, dietary fibre and fruit, vegetable, nut and legume content was obtained from food labels, company websites and manufacturers. Results were compared to criteria based on identifying core and non-core food groups and the criteria set by companies in the voluntary industry codes for marketing to children. Results Of the 116 unique food advertisements, 61% failed nutrient profiling and were considered 'unhealthy' foods. Of the advertisements that passed nutrient profiling, 64% were promoting core foods, while 93% of those that failed nutrient profiling were promoting non-core foods. Sixty-three per cent of advertisements that met the nutrition criteria outlined in the grocery manufacturers' company action plans passed nutrient profiling. Only one advertisement for fast food passed the fast food company criteria and nutrient profiling. Conclusions The Food Standards Australia New Zealand nutrient profiling criteria provide an independent assessment of the overall healthiness of a product and have potential to form the basis of nutrient criteria for regulating food marketing to children in Australia. Current criteria within voluntary self-regulatory initiatives are complex and lenient, and fail to cover many foods advertised. [ABSTRACT FROM AUTHOR]

Aim: To investigate and compare the level of nutrition knowledge of health professionals, patients with eating disorders and individuals without an eating disorder as controls. Methods: Participants were recruited online through an Australian and New Zealand professional eating disorder organisation and community eating disorder organisations and a university in Australia. Assessment was conducted online using the General Nutrition Knowledge Questionnaire and SCOFF. Demographic data were also collected. Results: Dietitians had greater nutrition knowledge than all other health professionals, except medical doctors. Psychologists and dietitians had similar knowledge for choosing everyday foods. Dietitians had greater nutrition knowledge than eating disorder patients and controls in all areas of nutrition knowledge, while other health professionals had similar knowledge to patients. Patients with eating disorders had greater knowledge of sources of nutrients than controls. Conclusions: Australian health professionals exhibited higher levels of nutrition knowledge than health professionals in previous studies in other countries. However, non-dietitian health professionals had similar levels of knowledge to individuals with eating disorders. Training and continuing education in nutrition is needed so health professionals can confidently identify when a patient has misleading information about nutrition and either correct the misinformation or refer the patient on to a qualified dietitian.

Aim: To investigate the bone health and associated risk factors of a group of South Asian women living in New Zealand. Studies on the Indian subcontinent suggest a high incidence of low bone mineral density in women with poor vitamin D status and low dietary calcium intake. Methods: Subjects were women of South Asian origin (n = 91) living in Auckland, New Zealand. Subjects were stratified by menopausal status. They completed a 4-day food diary, and provided a fasting blood sample. Bone mineral density was measured in the lumbar spine and proximal femur using dual X-ray densitometry. Results: Mean age of premenopausal (n = 71) and postmenopausal (n = 20) women was 39.8 ± 7.8 and 55.3 ± 5.4 years, respectively. Osteoporosis ( T-score ≤−2.5) was present in 32% of postmenopausal and 3% of premenopausal subjects, but only in the lumbar spine. Adequate 25(OH)D levels (>50 nmol/L) were found in only 22% of premenopausal, and 26% of postmenopausal women. A body mass index in the overweight or obese category was found in 61% of premenopausal and 75% of postmenopausal women. Conclusion: The high incidence of osteoporosis in the postmenopausal group could be associated with the early age of oophorectomy or menopause together with low vitamin D status.
