Functional foods have demonstrated potential in preventing gastrointestinal and musculoskeletal (osteo-related) disorders; however, evidence from cross-sectional studies in adults remains limited. This study aimed to examine the relationship between the frequency of functional food consumption and the prevalence of gastrointestinal and osteo-related conditions among adults in Bangladesh.

Cross-sectional study.

A face-to-face interview was conducted in Southern Bangladesh.

A total of 959 adults participated. Socio-demographic characteristics, lifestyle factors, health status and patterns of functional food consumption were collected using a structured questionnaire.

The prevalence of gastrointestinal and musculoskeletal (osteo-related) diseases, as well as their associations with the frequency of functional food consumption, were assessed using binary logistic regression.

Gastrointestinal and musculoskeletal (osteo-related) diseases were reported by 55.4% and 44.1% of participants, respectively. Multivariate logistic regression showed that several functional foods were associated with lower odds of gastrointestinal conditions, including regular seed intake (OR=0.35, p=0.034), weekly fibre-rich foods (OR=0.48, p=0.021), weekly probiotics (OR=0.26, p=0.012), monthly probiotics (OR=0.33, p

The consumption of functional foods, particularly seeds, probiotics, fibre-rich foods, nuts, tea/coffee and natural products were associated with a lower risk of gastrointestinal and musculoskeletal diseases in adults. These findings provide robust evidence to inform future prospective studies and support public health strategies in Bangladesh aimed at promoting the consumption of functional foods to prevent diet-related health conditions.

The rising burden of non-communicable diseases (NCDs), including mental health disorders (MHDs) such as anxiety and depression, poses a significant public health challenge globally. Evidence suggests that both diabetes and hypertension, the two most prevalent NCDs, are linked to a higher prevalence of MHDs. However, there is a lack of evidence on prevalence of generalised anxiety disorder (GAD) and depression among adults living with both diabetes and hypertension in Bangladesh. We aimed to assess the prevalence of GAD and depression and explore the associated factors among adults living with diabetes and hypertension comorbidity in rural Bangladesh.

We implemented a cross-sectional study.

The study was conducted in Chirirbandar, a sub-district of Dinajpur, Bangladesh.

We interviewed a total of 387 adults living with diabetes and hypertension comorbidity.

We had two primary outcome measures: GAD and depression. Individuals scoring ≥10 on the General Anxiety Disorder-7 scale were considered as having GAD and individuals scoring ≥10 on the Patient Health Questionnaire-9 scale were considered as having depression. The outcome variables were dichotomised based on these scores.

The prevalence of GAD was 7.24% (95% CI 5.04 to 10.29). Education level (grades 5–9) (adjusted OR (AOR): 3.40, 95% CI 1.26 to 9.19) and household wealth status (highest wealth tertile) (AOR: 0.12, 95% CI 0.02 to 0.62) were associated with GAD. The prevalence of depression was 17.83% (95% CI 14.32 to 21.98). Socioeconomic factors associated with depression included unemployment (AOR: 3.26, 95% CI 1.05 to 10.10) and household wealth status (highest wealth tertile) (AOR: 0.45, 95% CI 0.21 to 0.98). Higher odds of depression were also observed among participants with controlled hypertension (AOR: 3.88, 95% CI 1.81 to 8.35). Other factors, such as tobacco use, dietary diversity and physical activity, were not associated with GAD or depression.

A high prevalence of GAD and depression was observed among adults living with diabetes and hypertension comorbidity. The findings from the study emphasise the need for integration of mental health services into the existing non-communicable disease care. The identified factors associated with GAD or depression should be considered to develop targeted interventions for people with hypertension and diabetes comorbidity in Bangladesh.

This study aimed to investigate the association between food insecurity and dietary intake with anxiety and depression among residents of underserved urban settlements in Bangladesh.

This cross-sectional study was used to collect data from participants through face-to-face interviews using structured questionnaires. Food security status was assessed using the Household Food Insecurity Access Scale, while anxiety and depression levels were measured using the Generalised Anxiety Disorder-7 and Patient Health Questionnaire-9, respectively. Dietary intake was evaluated through a 24-hour dietary recall and Food Frequency Questionnaire method.

Five districts located within the Khulna Division of Bangladesh.

Residents of underserved urban areas in Bangladesh (n=749), aged ≥18 years old.

Results indicated that 22.1%, 74.6% and 44.5% of participants experienced severe food insecurity, mild to moderate food insecurity and low Household Dietary Diversity Score, with a significant portion also showing symptoms of anxiety (57.1%) and depression (57.9%). Food insecurity and Household Dietary Diversity Score were found to be positively associated with both anxiety (p

These findings highlight that food insecurity not only affects dietary habits but also exacerbates mental health outcomes. Addressing food insecurity and balanced dietary intake could therefore contribute to better mental health outcomes and overall well-being in underserved communities. Policymakers should prioritise comprehensive strategies that ensure access to nutritious foods and provide mental health support to vulnerable groups.
