Food insecurity and insomnia‐related symptoms among adults from low‐ and middle‐income countries

Abstract

Summary Little is known about the relationship between food insecurity and sleep problems in low‐ and middle‐income countries, while the mediators of this association are largely unknown. Therefore, we investigated the association between food insecurity and insomnia‐related symptoms in six low‐ and middle‐income countries (i.e., China, Ghana, India, Mexico, Russia, South Africa), and the potential mediators of this relationship. Cross‐sectional, nationally representative data from the Study on Global AGEing and Adult Health (2007–2010) were analysed. Past 12‐month food insecurity was assessed with two questions on the frequency of eating less, and on hunger owing to a lack of food. Insomnia‐related symptoms referred to severe or extreme sleep problems in the past 30 days. Multivariable logistic regression and mediation analysis were conducted. Data on 42,489 adults aged ≥18 years were analysed (mean [standard deviation] age 43.8 [14.4] years; 50.1% females). The prevalence of any food insecurity and insomnia‐related symptoms was 11.9% and 4.4%, respectively. After adjustment, compared with no food insecurity, moderate (odds ratio = 1.53, 95% confidence interval = 1.11–2.10) and severe food insecurity (odds ratio = 2.35, 95% confidence interval = 1.56–3.55) were significantly associated with insomnia‐related symptoms. Anxiety, perceived stress, and depression mediated 27.7%, 13.5%, and 12.5% of the relationship between any food insecurity and insomnia‐related symptoms, respectively (total percentage = 43.3%). Food insecurity was positively associated with insomnia‐related symptoms in adults from six low‐ and middle‐income countries. Anxiety, perceived stress, and depression explained a substantial proportion of this relationship. Addressing food insecurity itself or the identified potential mediators among people with food insecurity may lead to a reduction in sleep problems among adults in low‐ and middle‐income countries, pending confirmation with longitudinal studies.

Causal relationship between insomnia and both socio-economic status and individual behavior: a Mendelian randomization analysis

“…A high degree of heterogeneity was found in the meta-analysis, indicating that research results should be carefully considered [19] . There was also a study shows a positive correlation between food insecurity and insomnia related symptoms among adults in low-income and middle-income countries [20] . This is consistent with our research results,which indicates that SES has a profound impact on insomnia.…”

Anxiety and Sleep Mediate the Effect of Food Insecurity on Depression in Single Parents in Ghana: a cross-sectional study

“…Food insecurity may lead to disordered dietary patterns, which can potentially reduce the energy required to initiate sleep or interfere with sleep quality [12]. Moreover, poor nutritious food due to food insecurity may cause gastroesophageal re ux, in which stomach acid frequently ows back toward and irritates the esophagus [15]. Again, single parents facing food insecurity may employ coping mechanisms such as working multiple jobs or taking on additional responsibilities to make ends meet.…”

“…The association of food insecurity with depression can be explained by generalized anxiety disorder [8, 13,14] and sleep problems [12,15,16]. Studies on the effects of household food insecurity on depression in this population are limited.…”
