Association of health literacy and other risk factors with glycemic control among patients with type 2 diabetes in Kuwait: A cross-sectional study.

BACKGROUND: Poor health literacy (HL) has received much attention recently as a risk factor for poor health outcomes especially among patients with chronic diseases. The degree to which HL affects health outcomes is unknown among patients with type 2 diabetes mellitus (T2DM) in Kuwait. This study aimed to investigate the association between HL and glycated hemoglobin (HbA1c) among patients with T2DM. METHODS: 356 patients with T2DM were selected from 27 primary care clinics covering the state of Kuwait. HL was measured by the Short Test of Functional Health Literacy in Adults (STOFHLA). Prevalence of uncontrolled HbA1c was estimated and its association with HL was modeled and tested using Poisson regression with log-link function and robust variance-covariance matrix, while adjusting for several confounders. RESULTS: The prevalence of uncontrolled HbA1c was 77.8%. Among those with inadequate or marginal HL, about 50.7% have uncontrolled HbA1c. The prevalence of uncontrolled HbA1c among those on diet alone was 36.3% lower compared to those on mixed treatment regimen (APR = 0.637, 95% CI: 0.455-0.891, PV = 0.008). The prevalence of uncontrolled HbA1c among patients on oral hypoglycemic (OH) drugs alone was 22.3% lower compared to those on mixed treatment (OH plus Insulin) regimen (APR = 0.777, 95% CI: 0.697-0.865, PV < 0.001). For every one-year increase in age, there is 1.4% reduction in the prevalence of uncontrolled HbA1c (APR = 0.986, 95% CI: 0.978-0.994, PV < 0.001). For one STOFHLA score increase, there is 0.3% reduction in the prevalence of uncontrolled HbA1c (APR = 0.997, 95% CI: 0.994-1.00, PV = 0.055). Finally, for every year increase since T2DM onset, there is 1.1% increase in the prevalence of uncontrolled HbA1c (APR = 1.011, 95% CI: 1.003-1.019, PV = 0.008). CONCLUSIONS: The prevalence of uncontrolled HbA1c among patients with T2DM in Kuwait is high. Half of T2DM with inadequate or marginal HL have uncontrolled HbA1c. Patients on diet alone or OH alone have lower prevalence of uncontrolled HbA1c compared to those on mixed treatment regimen. Older T2DM patients or those with higher STOFHLA score have lower prevalence of uncontrolled HbA1c, while those with longer T2DM onset have higher prevalence of uncontrolled HbA1c. Future interventions should focus on younger patients, improve HL, and establish better communications between physicians and patients with T2DM for better glycemic control.

Psoriasis Among Adolescents in Kuwait and the Role of Siblings, Breastfeeding, and Household Cat and Secondhand Smoke Exposure: A Cross-Sectional Study.

INTRODUCTION: Globally, the epidemiology of psoriasis is poorly understood, and most countries lack essential epidemiologic data regarding disease burden and its determinants. This study sought to estimate the prevalence of psoriasis among adolescents in Kuwait and assess its association with different risk factors, including obesity, sibship size, breastfeeding, and exposure to household secondhand smoke (SHS) and pets. METHODS: Schoolchildren aged 11-14 years (n = 3864) were enrolled in a cross-sectional study. Lifetime and current (past 12 months) prevalence of psoriasis were ascertained according to ever having a history of doctor-diagnosis plus current active lesion(s) and/or current use of treatment of psoriasis. Associations were assessed using Poisson regression with robust variance estimation, and adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) were estimated. RESULTS: The lifetime and current prevalence of psoriasis were estimated to be 3.6% (136/3806) and 1.1% (42/3806), respectively. Commonly reported anatomical sites affected by psoriasis included scalp (47.6%) and the extensor surface of the knees (50%) and elbows (38.1%). Household SHS exposure was associated with increased lifetime psoriasis (aPR = 1.41, 95% CI 1.07-1.98), and showed a trend for association with current psoriasis (1.77, 0.89-3.53). Similarly, cat-keeping during infancy was associated with lifetime psoriasis (1.96, 1.14-3.37), and demonstrated a trend for association with current psoriasis (1.49, 0.52-1.98). In contrast, breastfeeding was associated with a decreased lifetime psoriasis (0.62, 0.44-0.89), but was not associated with current psoriasis. Trend analyses showed that the prevalence of lifetime and current psoriasis increased with increasing numbers of total, older, and younger siblings. CONCLUSIONS: Psoriasis affects a considerable proportion of schoolchildren in Kuwait. Interestingly, psoriasis prevalence was related to risk factors also found in allergic diseases, such as exposure to SHS, cat-keeping in infancy, breastfeeding, and sibship size, possibly suggesting a role of immune dysregulation.

Prevalence of health literacy and its correlates among patients with type II diabetes in Kuwait: A population based study.

AIMS: The purpose of this study is to estimate the prevalence of health literacy among patients with type II diabetes and investigate its association with several covariates. No studies were conducted in the Arabian Gulf region characterizing such factors for this population. METHODS: A cross sectional study was implemented in which 359 type II diabetes patients were recruited from diabetes centers across Kuwait. Health literacy was measured by STOFHLA. Multivariate linear regression was applied to investigate the relationship between health literacy and several covariates. RESULTS: About 44.5% had inadequate, 19.5% marginal, and 35.5% adequate health literacy. Patients with inadequate health literacy were more likely to be older, females, widowed, low education, with income less than 500 KD/month. Multivariate linear regression indicated residence, nationality, education level, and age were significantly associated with health literacy. Adding marital status and gender, hierarchical linear regression revealed that 43.4% of the variability was accounted for. CONCLUSION: Inadequate health literacy is high in Kuwait. Interventions should be implemented to improve health literacy. This will reduce the prevalence of diabetes-related complications, produce better diabetes outcomes, and improve patients' quality-of-life. Health literacy should be an integral part to health promotion and chronic diseases' management programs in Kuwait.
