Understanding the role of family functioning, dietary adherence, and culture on glycemic control among adults with type 2 diabetes: A mediation and moderation analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFamilies and cultural contexts can impact dietary adherence and glycemic control of type 2 diabetes (T2D). Yet little is known about these relationships in Africa, where poor dietary adherence and glycemic control are prevalent. To address this gap, this study investigated whether dietary adherence mediates family functioning and glycemic control among T2D adults in Benin, West Africa. We also explored whether cultural identity affected the association between family functioning and dietary adherence.
methodsA cross-sectional study of 512 T2D patients from six health centers was conducted to assess: 1) family functioning with the 12-item McMaster Family Assessment Device-General Functioning Subscale (FAD-GF); 2) dietary adherence via the Perceived Dietary Adherence Questionnaire (PDAQ); and 3) cultural identity with the 12-item Multigroup Ethnic Identity Measure (MEIM). The three-month glycemic control was determined with Glycated Hemoglobin - HbA1c. Mediation and moderation analyses were conducted using Stata's structural equation model (SEM).
resultsHealthy family functioning, good dietary adherence and good glycemic control rates were 56.8%, 33%, and 30.5% respectively. Path analysis showed that healthy family functioning was significantly associated with lower HbA1c levels (-0.34, 95% CI: [-0.72, -0.03]), and there was a significant indirect effect via greater dietary adherence (-0.12, 95% CI: [-0.22, -0.01]). However, cultural identity did not significantly impact the relationship between family functioning and dietary adherence.
conclusionsOur study revealed that family functioning, adherence to dietary recommendations, and glycemic control are interconnected in adults with T2D. Interventions should target modifiable factors like dietary adherence and address relevant risk and resilience sources to improve glycemic control in urban African families.
