The Centre for Epidemiologic Studies Depression Scale (score\u226516;NWAHS) and the Beck Depression Inventory 1A (score\u226513;FAMAS) were used to characterise mild-severe depressive symptoms. The Generalised Anxiety Disorder questionnaire was used to identify moderate-severe anxiety (score 10\u201321).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec003\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of 1,320 participants (male n\u2009=\u2009797), 62.4% (n\u2009=\u2009824) were aged \u226565years (range 36\u2212100 years), and 37.8% reported workforce participation at the time of the COVID-19 survey. Depressive and anxiety symptoms were observed for participants aged 35\u221254years (OR=1.92,95%CI\u2009=\u20091.01\u20133.67), financial stress (1.81,1.02\u20133.21), change in overall food intake (increase and decrease), social support none\/sometimes(2.74,1.48\u20135.07), low control\/mastery since COVID-19 (6.00,3.37\u201310.6) and poor sleep during restrictions (7.94,4.25\u201314.8), independent of previous depressive symptoms (8.30,1.9\u201313.2). Change in mental health status from pre-COVID to COVID-19 restriction was associated with sex (p\u2009=\u20090.013) and age (p\u2009&lt;\u20090.001), such that females and younger participants (35\u221254yr) reported depressive symptoms at both times.
