Diet quality fluctuates throughout one’s adulthood, yet it remains unclear how long-term diet quality changes are related to type 2 diabetes mellitus (T2DM) and its biomarkers. We aimed to examine the association of long-term diet quality with T2DM and its biomarkers. Diet quality was assessed by the revised DBI-07, in which diet quality distance levels (DQD) represented the overall diet quality. Participants were clustered into classes sharing similar DQD levels using latent class mixed model. We used Cox regression and random effect linear regression to assess DQD trajectories’ association with T2DM and its biomarkers. Three DQD trajectories were derived: moderate to gradual decrease, high to moderate, high stable DQD level representing 2.14%, 6.18% and, 91.68% of the population. Compared to class 1, class 2 and 3 were associated with an increased risk of T2DM [HR=4.40; 95%CI: 2.02-9.59]; [HR=3.68; 95% CI: 2.11-6.43]. When class 3 was used as a reference, class 1 was also associated with an increased risk of TDM [HR=2.71; 95%CI: 1.55-4.73]. Our findings suggest that a long-term unhealthy diet is associated with an increased risk of T2DM. Gradually reducing DQD level may not make a difference, which establishes the importance of promoting healthy eating habits at early adulthood.
The objective of this study was to determine whether adherence to the new WHO recommendations for the frequency and timing of antenatal care (ANC) contacts was associated with receiving quality prenatal care in Cameroon. The 2018 Cameroon Demographic and Health Survey yielded a weighted sample of 5,694 women aged 15 to 49 years for analysis. We found that 8.9% of women had at least eight ANC contacts, with 47.3% of those occurring during the first trimester. Overall, 28.3% (95% CI [26.4, 30.3]) of the women received all eight ANC interventions studied. Women who made at least eight ANC contacts prior to delivery had a higher chance of receiving the full set of interventions (AOR = 1.41; 95% CI [1.00, 1.99]). Even among women who started ANC in the second trimester, those who made at least eight contacts were more likely than those who made fewer contacts to receive the full set of interventions. Furthermore, women who had their first contact later in the second (AOR = 0.85; 95% CI [0.72, 0.99]) or third trimester (AOR = 0.33; 95% CI [0.19, 0.57]) were less likely to receive the full set of interventions. According to our findings, Cameroonian women who followed the new global recommendations for prenatal care were more likely to receive quality prenatal care before giving birth. To have a positive pregnancy experience, however, more women must begin ANC in the first trimester and have at least eight contacts with health care providers before delivery.
Accumulating studies have shown that chronic exposure to iAs correlates with an increased incidence of diabetes. In recent years, miRNA dysfunction has emerged both as a response to iAs exposure and independently as candidate drivers of metabolic phenotypes such as T2DM. However, few miRNAs have been profiled during the progression of diabetes after iAs exposure in vivo. In the present study, high iAs (10 mg/L NaAsO2) exposure mice models of C57BKS/Leprdb (db/db) and C57BLKS/J (WT) were established through the drinking water, the exposure duration was 14 weeks. The results showed that high iAs exposure induced no significant changes in FBG levels in either db/db or WT mice. FBI levels, C-peptide content and HOMA-IR levels were significantly increased, and glycogen levels in the livers were significantly lower in arsenic-exposed db/db mice. HOMA-β% was decreased significantly in WT mice exposed to high iAs. In addition, more different metabolites were found in the arsenic-exposed group than the control group in db/db mice, mainly involved in the lipid metabolism pathway. Highly expressed glucose, insulin, and lipid metabolism-related miRNAs were selected, including miR-29a-3p, miR-143-3p, miR-181a-3p, miR-122-3p, miR-22-3p and miR-16-3p. And a series of target genes were chosen for analysis, such as ptp1b, irs1, irs2, sirt1, g6pase, and pepck. The results showed that, the axles of miR-181a-3p-irs2, miR-181a-3p-sirt1, miR-22-3p-sirt1, and miR-122-3p-ptp1b in db/db mice, and miR-22-3p-sirt1, miR-16-3p-glut4 in WT mice could be considered as promising targets to explore the mechanisms and therapeutic aspects of T2DM after exposure to high iAs.
