Iron deficiency is a concern in both developing and developed (industrialized) countries; and young women are particularly vulnerable. This review investigates dietary determinants of and possible solutions to iron deficiency in young women living in industrialized countries. Dietary factors including ascorbic acid and an elusive factor in animal protein foods (meat; fish and poultry) enhance iron absorption; while phytic acid; soy protein; calcium and polyphenols inhibit iron absorption. However; the effects of these dietary factors on iron absorption do not necessarily translate into an association with iron status and iron stores (serum ferritin concentration). In cross-sectional studies; only meat intake has consistently (positively) been associated with higher serum ferritin concentrations. The enhancing effects of ascorbic acid and meat on iron absorption may be negated by the simultaneous consumption of foods and nutrients which are inhibitory. Recent cross-sectional studies have considered the combination and timing of foods consumed; with mixed results. Dietary interventions using a range of focused dietary measures to improve iron status appear to be more effective than dietary approaches that focus on single nutrients or foods. Further research is needed to determine optimal dietary recommendations for both the prevention and treatment of iron deficiency.

The number of people of advanced age (85 years and older) is increasing and health systems may be challenged by increasing health-related needs. Recent overseas evidence suggests relatively high levels of wellbeing in this group, however little is known about people of advanced age, particularly the indigenous Māori, in Aotearoa, New Zealand. This paper outlines the methods of the study Life and Living in Advanced Age: A Cohort Study in New Zealand. The study aimed to establish predictors of successful advanced ageing and understand the relative importance of health, frailty, cultural, social & economic factors to successful ageing for Māori and non-Māori in New Zealand.

Objectives: The purpose of this study was to investigate the knowledge and health beliefs regarding osteoporosis risk factors of New Zealand women aged 20–49 years.Design: A descriptive, web-based survey.Subjects: An opportunistic sample of 622 women aged between 20 and 49 years living in Auckland, New Zealand was recruited by email.Results: There was a moderate level of knowledge about osteoporosis risk factors among the women surveyed, with a mean total score for all subjects of 16.4 (standard deviation (SD) 4.0) out of a possible 26 correct responses. Mean scores for osteoporosis knowledge were statistically different by age group, with women aged 40–49 years scoring higher than those aged 30–39 years and 20–29 years (17.3 (SD 4.0), 16.4 (SD 4.1) and 15.8 (SD 3.9), respectively, P < 0.001). Overall, about a third of the women perceived that they were likely to develop osteoporosis and 22% believed the disease to be potentially crippling. Most women were aware of the benefits of exercise and optimal calcium nutrition in preventing osteoporosis. Few women perceived barriers to exercise participation and eating calcium-rich foods. Older women (40–49 years) were more motivated to take care of their health than younger women (P < 0.001). A large percentage of subjects (77%) thought that calcium-rich foods contained too much cholesterol.Conclusions: Despite reporting higher than average educational attainment and health consciousness, these women demonstrated average levels of knowledge about osteoporosis risk factors. They had low feelings of susceptibility towards development of osteoporosis, but most considered it to be a serious disease.

To establish the prevalence of high nutrition risk and associated health and social risk factors for New Zealand Māori and non-Māori in advanced age. A cross sectional analysis of inception cohorts to LiLACS NZ. Bay of Plenty and Lakes region of the North Island, New Zealand. 255 Māori and 400 non- Māori octogenarians. Nutrition risk was assessed using a validated questionnaire Seniors in the Community: Risk Evaluation for Eating and Nutrition (SCREEN II). Demographic, social, physical and health characteristics were established using an interviewer administered questionnaire. Health related quality of life (HRQOL) was assessed with the SF-12, depressive symptoms using the GDS-15. Half (49%) of Māori and 38% of non-Māori participants were at high nutrition risk (SCREEN II score <49). Independent risk factors were for Māori younger age (p=0.04), lower education (p=0.03), living alone (p<0.001), depressive symptoms (p=0.01). For non- Māori high nutrition risk was associated with female gender (p=0.005), living alone (p=0.002), a lower physical health related quality of life (p=0.02) and depressive symptoms (p=0.002). Traditional risk factors apply to both Māori and non-Māori whilst education as indicative of low socioeconomic status is an additional risk factor for Māori. High nutrition risk impacts health related quality of life for non-Māori. Interventions which socially facilitate eating are especially important for women and for Māori to maintain cultural practices and could be initiated by routine screening.

The ageing of the population globally and in New Zealand (NZ) was the main driver for this study. In Aoteoroa, New Zealand, little is known about Māori and non-Māori of advanced age, yet population projections predict a trebling of the number of Māori and a doubling of non-Māori octogenarians in the next 10 years. 1

In women, the menopausal transition is characterized by acid-base imbalance, estrogen deficiency and rapid bone loss. Research into nutritional factors that influence bone health is therefore necessary. In this study, the relationship between nutrient patterns and nutrients important for bone health with bone mineral density (BMD) was explored. In this cross-sectional analysis, 101 participants aged between 54 and 81 years were eligible. Body composition and BMD analyses were performed using dual-energy X-ray absorptiometry (DXA). Nutrient data were extracted from a 3-day diet diary (3-DDD) using Foodworks 9 and metabolic equivalent (MET-minutes) was calculated from a self-reported New Zealand physical activity questionnaire (NZPAQ). Significant positive correlations were found between intakes of calcium (p = 0.003, r = 0.294), protein (p = 0.013, r = 0.246), riboflavin (p = 0.020, r = 0.232), niacin equivalent (p = 0.010, r = 0.256) and spine BMD. A nutrient pattern high in riboflavin, phosphorus and calcium was significantly positively correlated with spine (p < 0.05, r = 0.197) and femoral neck BMD (p < 0.05, r = 0.213), while the nutrient pattern high in vitamin E, α-tocopherol, β-carotene and omega 6 fatty acids was negatively correlated with hip (p < 0.05, r = −0.215) and trochanter BMD (p < 0.05, r = −0.251). These findings support the hypothesis that a nutrient pattern high in the intake of vitamin E, α-tocopherol and omega 6 fatty acids appears to be detrimental for bone health in postmenopausal women.
