The prevalence of vegetarians, vegans and other dietary patterns that exclude some animal-source foods in a representative sample of New Zealand adults.

OBJECTIVE: This study aimed to estimate the prevalence of vegetarians, vegans and other dietary patterns that exclude some animal-source foods in New Zealand adults. We also examined socio-demographic and lifestyle correlates of these dietary patterns. DESIGN: The New Zealand Health Survey is a representative rolling cross-sectional survey of New Zealanders; data from the 2018/19 and 2019/20 waves were used for this analysis. Participants were asked if they completely excluded red meat, poultry, fish/shellfish, eggs or dairy products from their diet. SETTING: New Zealand. PARTICIPANTS: Adults, aged ≥ 15 years (n 23 292). RESULTS: The prevalence of red-meat excluders (2·89 %), pescatarians (1·40 %), vegetarians (2·04 %) and vegans (0·74 %) was low. After adjustment for socio-demographic and lifestyle factors, women (OR = 1·54, 95 % CI: 1·22, 1·95), Asian people (OR = 2·56, 95 % CI: 1·96, 4·45), people with tertiary education (OR = 1·71, 95 % CI: 1·18, 2·48) and physically active people (OR = 1·36, 95 % CI: 1·04, 1·76) were more likely to be vegetarian/vegan. Those aged ≥ 75 years (OR = 0·28, 95 % CI: 0·14, 0·53) and current smokers (OR = 0·42, 95 % CI: 0·23, 0·76) were less likely to be vegetarian/vegan. Similar associations were seen between socio-demographic and lifestyle factors and the odds of being a red-meat excluder/pescatarian. CONCLUSIONS: Approximately 93 % of New Zealand adults eat red meat and a very small number exclude all animal products from their diets. The Eating and Activity Guidelines for New Zealand adults recommend a plant-based diet with moderate amounts of animal-source foods. A comprehensive national nutrition survey would provide detailed information on the amount of red meat and other animal-source foods that the New Zealand population currently consumes.

The Rotator Cable Does Not Stress Shield the Crescent Area During Shoulder Abduction.

BACKGROUND: It is accepted by the orthopaedic community that the rotator cable (RCa) acts as a suspension bridge that stress shields the crescent area (CA). The goal of this study was to determine if the RCa does stress shield the CA during shoulder abduction. METHODS: The principal strain magnitude and direction in the RCa and CA and shoulder abduction force were measured in 20 cadaveric specimens. Ten specimens underwent a release of the anterior cable insertion followed by a posterior release. In the other 10, a release of the posterior cable insertion was followed by an anterior release. Testing was performed for the native, single-release, and full-release conditions. The thicknesses of the RCa and CA were measured. RESULTS: Neither the principal strain magnitude nor the strain direction in either the RCa or the CA changed with single or full RCa release (p ≥ 0.493). There were no changes in abduction force after single or full RCa release (p ≥ 0.180). The RCa and CA thicknesses did not differ from one another at any location (p ≥ 0.195). CONCLUSIONS: The RCa does not act as a suspension bridge and does not stress shield the CA. The CA primarily transfers shoulder abduction force to the greater tuberosity. CLINICAL RELEVANCE: The CA is important in force transmission during shoulder abduction, and efforts should be made to restore its continuity with a repair or reconstruction.

Quality of care in people requiring hospital admission for gout in Aotearoa New Zealand: a nationwide analysis.

BACKGROUND: The quality of care for patients admitted with a primary diagnosis of gout, both before and after admission, has not been systematically examined. AIMS: To understand national trends in hospital admission for a primary diagnosis of gout in Aotearoa New Zealand over the past 10 years and the quality of care for gout received by these patients before and after the admission. METHODS: Data from the Aotearoa New Zealand National Collections from 1 January 2007 to 31 December 2019 were analysed to determine rates of hospital admission for a primary diagnosis of gout. Admission data include cost-weight analysis, as well as quality of care data including gout-specific medication dispensing in the year prior and year after admission. RESULTS: There were 13 721 admissions with a primary diagnosis of gout over the analysis period, with an average cost per admission in 2019 of NZ$4301. The rate of admission per 100 000 population was highest in Pacific peoples followed by Maori. Although dispensing of any allopurinol increased in the year after admission, rates of regular allopurinol dispensing remained low; 38.1% for admissions in 2018. Patients who were younger (especially 20-44 years), not enrolled in a primary health organisation before admission and female had lower rate of regular allopurinol after admission. CONCLUSION: In this nationwide study, rates of admission for gout were highest in Pacific peoples and in Maori. Rates of regular allopurinol dispensing were low even after admission for a primary diagnosis of gout. These findings highlight the need for improvements in gout management in Aotearoa New Zealand, including in post-discharge planning from secondary care inpatient services.

Typhoid fever: hurdles to adequate hand washing for disease prevention among the population of a peri-urban informal settlement in Fiji.

PROBLEM/CONTEXT: The Pacific island nation of Fiji Islands has high rates of endemic typhoid fever which is difficult to diagnose and often underreported. However, the majority of cases are preventable through use of safe water; adequate sanitation; vaccination; and, most sustainable of all, simple hygienic behaviour, such as hand washing with soap (HWWS). Despite many attempts by public health authorities, little progress has been made in the area of environmental adaptation and behaviour change. ACTION: To explore perceptions of typhoid fever risk among urban squatters and behavioural determinants surrounding HWWS, indigenous Fijians living in informal settlements with high typhoid fever incidence were invited to participate in focus group discussions. In-depth interviews were conducted with community leaders. OUTCOME: Perceptions of typhoid fever suggest confusion about risk factors, symptoms and communicability. Environmental barriers for hand washing were related to water and soap access. Standard social marketing approaches have been trialled with little clear evidence of impact. Despite this, we continue to advocate for the social and cultural determinants of typhoid prevention to remain central to future public health strategies. DISCUSSION: Despite behaviour change being notoriously difficult, we argue that community-driven behaviour adaptation initiatives based on sound epidemiological evidence and health communication theory are likely to have significant impact and greater likelihood of sustainability.
