The prevalence of household food insecurity in Newfoundland and Labrador (NL) fell sharply between 2007 and 2011, but it appears to have risen since then. Our objective was to compare the prevalence of food insecurity between 2011-2012 and 2017-2018 in relation to population socio-demographic characteristics.
Our analytic sample comprised all NL households in the Canadian Community Health Survey (CCHS) cycles 2011-2012 and 2017-2018, n = 6800. We stratified the prevalence of household food insecurity for each cycle by socio-demographic characteristics and applied multivariable logistic regression models to determine food insecurity odds in 2017-2018 compared with 2011-2012 after controlling for socio-demographic covariates. Interactions of covariates with survey cycle were tested and models stratified when warranted.
The prevalence of food insecurity rose from 12.0% (95% CI 10.5, 13.6) in 2011-2012 to 14.7% (95% CI 13.1, 16.6) in 2017-2018. After adjusting for household socio-demographic variables, the odds of food insecurity was 1.49 (95% CI 1.27, 1.75) in 2017-2018. The prevalence of food insecurity had increased significantly among unattached individuals, renters, households with low educational attainment, and households with income above the Low Income Measure, with concomitant increases in the contribution of these groups to the total provincial prevalence of food insecurity in 2017-2018 compared with that in 2011-2012.
The odds of food insecurity among NL households increased significantly from 2011-2012 to 2017-2018. Given the serious negative health implications of household food insecurity, the province should draw on the lessons from its earlier success in food insecurity reduction to reverse the current trend.
纽芬兰和拉布拉多省（NL）的家庭粮食不安全现象在 2007 年至 2011 年期间急剧下降，但此后似乎有所上升。我们的目的是比较 2011-2012 年和 2017-2018 年与人口社会人口统计学特征相关的粮食不安全发生率。
我们的分析样本包括加拿大社区健康调查（CCHS）2011-2012 年和 2017-2018 年周期中的所有 NL 家庭，n=6800。我们按社会人口统计学特征对每个周期的家庭粮食不安全发生率进行分层，并应用多变量逻辑回归模型，在控制社会人口学协变量后，确定 2017-2018 年与 2011-2012 年相比的粮食不安全几率。测试了协变量与调查周期的交互作用，并在必要时对模型进行分层。
粮食不安全的发生率从 2011-2012 年的 12.0%（95%CI 10.5，13.6）上升到 2017-2018 年的 14.7%（95%CI 13.1，16.6）。在调整家庭社会人口学变量后，2017-2018 年的粮食不安全几率为 1.49（95%CI 1.27，1.75）。在无配偶的个人、租房者、教育程度较低的家庭和收入高于低收入衡量标准的家庭中，粮食不安全的发生率显著增加，而这些群体对 2017-2018 年全省粮食不安全总发生率的贡献也相应增加，与 2011-2012 年相比。
NL 家庭的粮食不安全几率从 2011-2012 年到 2017-2018 年显著增加。鉴于家庭粮食不安全对健康的严重负面影响，该省应借鉴其在减少粮食不安全方面早期成功的经验教训，扭转当前的趋势。
