Development and validation of a nomogram prediction model for hypertension-diabetes comorbidity based on chronic disease management in the community

PURPOSE

​Develop and validate a nomogram prediction model for hypertension-diabetes comorbidities based on chronic disease management in the community.

PATIENTS AND METHODS

The nomogram prediction model was developed in a cohort of 7200 hypertensive patients at a community health service center in Hongshan District, Wuhan City. The data were collected from January 2022 to December 2022 and randomly divided into modeling and validation groups at a 7:3 ratio. The Lasso regression model was used for data dimensionality reduction, feature selection, and clinical test feature construction. Multivariate logistic regression analysis was used to build the prediction model.

RESULTS

The application of the nomogram in the verification group showed good discrimination, with an AUC of 0.9205 (95% CI: 0.8471-0.9527) and a good calibration effect. Decision curve analysis demonstrated that the predictive model was clinically useful.

CONCLUSION

This study presents a nomogram prediction model that incorporates age, waist-height ratio and elevated density lipoprotein cholesterol (HDL-CHOLESTEROL), which can be used to predict the risk of codeveloping diabetes in hypertensive patients.

Lipid profile of hyperlipidemic males after supplementation of multigrain bread containing sunflower (Helianthus annuus) seed flour

Sunflower seeds are produced and consumed worldwide due to their richness in heart friendly nutrients in the bakery products. Its effect on reducing the incidences of cardio vascular diseases have not been studied, through supplementary studies therefore present supplementation study was planned in which five samples of bread were prepared by using various multigrain flours and sunflower seed flour at five different levels of 2.5, 5, 7.5, 10 and 12.5%. The bread sample supplemented with 7.5% sunflower seed flour was found to be highly acceptable. Sunflower seeds were roasted at 60 °C for 10-15 min. Chemical analysis of sunflower seed flour (raw and roasted) and highly acceptable bread pertaining to proximate composition, in vitro protein digestibility, antioxidant activity, bioactive compounds, essential fatty acids and minerals was done using standard methods. Roasting of seeds resulted in significant increase in carbohydrates, protein digestibility, phosphorus, magnesium and copper contents. The most acceptable sample had good amount of energy (324.48 kcal), protein (10.61 g), fat (2.92 g), fibre (11.36 g), ash (3.29 g), antioxidant activity (12.13%), total phenols (31.54 mg), flavonoids (17.53 mg), omega 3 fatty acids (186.16 mg), omega 6 fatty acids (13,701.40 mg), phosphorus (68.74 mg), magnesium (28.13 mg) and copper (0.12 mg) per 100 g. Sixty hyperlipidemic males aged 30-50 years were supplemented with highly acceptable bread for four months. After the intervention period, mean daily intake of and nuts and oilseeds increased significantly (p < 0.01) and a significant increase (p < 0.01) in the intake of total fat, dietary fibre, PUFA, linoleic acid, ascorbic acid, alpha tocopherols and phosphorus was observed. The weight, BMI, total cholesterol, LDL cholesterol and triglycerides significantly reduced after the supplementation.

Prevalence of Hypertension and Associated Factors in Lubumbashi City, Democratic Republic of Congo: A Community-Based Cross-Sectional Study

BACKGROUND

Hypertension is the leading cause of cardiovascular disease morbidity and mortality worldwide. Its struggle involves knowing its prevalence. Insufficient data on hypertension in adults in Lubumbashi, Democratic Republic of Congo (DRC), prompted the conduct of this study. The objectives were to determine the prevalence of hypertension and to identify the associated factors in adults in Lubumbashi. Methodology. A cross-sectional study was carried out among 6,708 adults from October 15th to November 24th, 2018, in Lubumbashi. Anthropometric data, lifestyle, and medical history were collected. Hypertension was defined when the mean of the last two blood pressure (BP) measurements was greater than or equal for systolic (SBP) at 140 mmHg and for diastolic (DBP) at 90 mmHg or a history of taking antihypertensive medication whatever the value of the BP. Logistic regression was used to identify the relative effects of hypertension risk factors and all statistical tests were declared significant at a p value <0.05.

RESULTS

The female participants numbered 4479 (66.8%). The mean age of all participants was 47.9 ± 16.5 years. The mean SBP and DBP were 128.4 ± 25.9 mmHg and 79.1 ± 15.3 mmHg, respectively. The overall prevalence of hypertension was 33.6%. This prevalence was statistically higher in women than in men (34.5% vs. 31.7%; p=0.024). After logistic regression, the risk of hypertension increased with age >50 years (aOR = 5.85 [5.19-6.60]), overweight (aOR = 1.25 [1.11-1.41]), obesity (aOR = 1.25 [1.11-1.41]), central obesity (aOR = 1.37 [1.16-1.61]), diabetes mellitus (aOR = 2.19 [1.63-2.95]), alcohol consumption (aOR = 1.21 [1.05-1.39]), nonconsumption of vegetables (aOR = 1.35 [1.02-1.80]), and history of stroke (aOR = 2.57 [1.88-3.51]). Hypertension was inversely associated with being underweight (aOR = 0.68 [0.53-0.87]).

CONCLUSION

The prevalence of hypertension in the city of Lubumbashi is high as in other cities of the DRC and Africa. This situation requires the implementation of prevention, detection, and treatment programs for hypertension.

Prevalence of Hypertension and Associated Factors in Dire Dawa City, Eastern Ethiopia: A Community-Based Cross-Sectional Study

Background

Hypertension is a major cardiovascular risk factor that is linked with fatal complications and is an overwhelming global challenge. Primary prevention is a key to control hypertension with identification of major risk factors. This study was aimed at assessing the prevalence and factors associated with hypertension.

Methods

Community-based cross-sectional study was conducted among 903 adults aged 25 to 64 years in Dire Dawa City, East Ethiopia. Data were collected using World Health Organization (WHO) STEPwise approach to Surveillance (STEPS) for non-communicable disease (NCD) standard survey tool. Multivariate logistic regression models were used to identify relative effects of distal, proximal, and immediate risk factors of hypertension, and all statistical tests were declared significantly at P-value<0.05.

Results

The average SBP and DBP were 124.98±17.18 mmHg and 78.92±10.13 mmHg, respectively. The prevalence of hypertension was 24.43% (95% CI: 21.57, 27.28). Majority (51.64%) of adults were not aware of their elevated blood pressure status. hypertension was significantly associated with the age group 30-44 (aOR 3.61, 95% CI: 2.0, 6.55), 45-54 (aOR 5.36, 95% CI: 2.62, 10.91), and 55-64 (aOR 9.38, 95% CI: 4.73, 18.59), being unemployed (aOR 1.68, 95%CI: 1.03, 2.77), ever smoking (aOR 1.89, 95% CI: 1.04, 2.23), having abdominal obesity (aOR 1.72, 95% CI: 1.13, 2.64), and BMI≥25 kg/m² (aOR 1.48, 95%CI: 1.01, 2.15).

Conclusion

Moderately high prevalence of hypertension was observed among adults in study setting demonstrating a major public health problem. Majority of adults with hypertension in study setting were not aware of their elevated BP status highlighting the burden of the hidden morbidity and subsequent complications. Community level intervention and routine assessment of sociodemographic, behavioral, and biophysiological risk factors, screening, and diagnosis of NCDs should be institutionalized to address the occult burden.
