Eating Disorder and Other Psychiatric Hospitalizations in New Zealand During the COVID-19 Pandemic.

OBJECTIVE: An unprecedented rise in eating disorder presentations has been documented in several countries during the COVID-19 pandemic. We explored this phenomenon by analyzing nationwide psychiatric admissions over 5 years, controlling for demographic variables. METHODS: We retrospectively analyzed all hospitalizations in New Zealand with a primary psychiatric diagnosis from 2017 to 2021, using Poisson regression to calculate admission rates by diagnosis, before and during the pandemic. Using Fisher's exact test and Poisson modeling, national data were validated against a manually collected sample of eating disorder admissions. RESULTS: Eating disorder admissions rose significantly during the pandemic (RR 1.48, p < 0.0001), while other diagnoses remained unchanged or decreased slightly. Anorexia nervosa in 10 to 19-year-old females drove increases, with persistent elevations noted in the 10-14 age group. Pandemic-associated increases were more striking for Maori (RR 2.55), the indigenous Polynesian population, compared with non-Maori (RR 1.43). CONCLUSIONS: Eating disorder hospital presentations increased during the COVID-19 pandemic, while other psychiatric presentations to hospital remained relatively unchanged. Possible drivers include disrupted routines, barriers to healthcare access, altered social networks, and increased social media use. Clinical services require additional resources to manage the increased disease burden, especially in vulnerable pediatric and indigenous populations. Ongoing monitoring will be required to establish the time-course of pandemic-related clinical demand.

The impact of COVID-19 on eating disorder referrals and admissions in Waikato, New Zealand.

BACKGROUND: Several countries have reported increased demand for eating disorder services during the COVID-19 pandemic, particularly for adolescents. Within New Zealand, anecdotal and media reports suggest similar changes but are limited in scope and detail. We assessed eating disorder service demand in the Waikato district in relation to the COVID-19 pandemic. METHODS: We retrospectively analysed records of eating disorder admissions and referrals for both children (< 18 years) and adults (≥ 18 years) during 2019 and 2020 in the Waikato, a mixed urban-rural province in northern New Zealand (population 435,000). We analysed medical admission and outpatient referral rates, and referral acuity, in relation to the COVID-19 pandemic using Welch's t- and chi-square tests. RESULTS: 106 medical admissions met inclusion criteria (n = 37 in 2019; 69 in 2020). Admissions for eating disorders increased markedly following nationwide lockdown in March 2020 (RR = 1.7, p = 0.01), largely driven by increases in adult admissions (RR 2.0, p = 0.005). The proportion of 'new patient' admissions showed comparable increases for both children (RR = 2.0, p = 0.02) and adults (RR = 2.3, p = 0.03). Following lockdown, outpatient referrals increased in acuity (RR = 1.8, p = 0.047) and volume (RR = 1.6, p = 0.076) for children but not for adults. CONCLUSIONS: Our study confirms a pandemic-related increase in demand for eating disorder services in the Waikato region of New Zealand, consistent with findings reported overseas. We observed contrasting increases in admissions for adults and outpatient referrals for children, exacerbating resource constraints for already stretched services and compromising provision of timely care. The COVID-19 pandemic has been linked to increased numbers and worsening severity of eating disorders in several settings. In New Zealand, similar trends have been noted anecdotally. We assessed clinical records to calculate rates of eating disorder-related hospital admissions and outpatient referrals during 2019 and 2020. We found significant increases in hospital admissions related to COVID-19, particularly for adults, and greater proportions of both children and adults having a first-ever eating disorder-related admission. In outpatient services, young people were referred more frequently during the pandemic and were more physically unwell when referred. These results indicate increased demand for eating disorder services as a result of the pandemic and complement findings reported overseas.
