Prevalence of and Factors Associated With High Blood Pressure Among Adolescents in India

Hypertension care cascade and their determinants among older adolescents in India: evidence from a nationally representative cross-sectional survey

Adolescent hypertension in India is an emergent public health concern with lack of programmatic focus on regular screening amongst both individuals and healthcare providers. This study was conducted to assess the hypertension care cascade (prevalence, awareness, treatment and control status of hypertension) from nationally representative data. We used data from the demographic and health surveillance (DHS) comprising India's National Family Health Survey Fifth Round (2019-2021). The prevalence of hypertension among 204,054 older adolescents (15-19 years) was 5.08% (95% CI: 4.94-5.23%) wherein 42.26% (95% CI: 40.69-43.64%) were aware of their condition, 43.70% (95% CI: 41.73-45.70%) of those aware were receiving treatment, and 85.88% (95% CI: 83.83-87.71%) of those on treatment achieved blood pressure control. Overall, there were nearly 60% newly diagnosed hypertension cases detected on screening. Females had significantly lower odds, while those with diabetes and higher waist-hip ratio had significantly higher odds of having hypertension. The awareness of their hypertensive status was higher among females and rural residents, while it was lower among adolescents that were obese and tobacco smokers. Improved blood pressure control was associated with a lower waist-to-hip ratio. In conclusion, nearly five in every hundred older adolescents in India are clinically hypertensive with significantly higher odds linked with obesity and male gender. Awareness and utilization of antihypertensive treatment was lower than the classical rule of halves signifying deficiencies in hypertension screening and management strategies for older adolescents within the existing public health policy framework.

Prevalence of Hypertension and Its Associated Factors among Adolescents in Eastern Sudan: A Community-Based Study

BACKGROUND

Elevated blood pressure, or hypertension, is one of the main health problems among adolescents globally. However, there are limited data on hypertension among adolescents in Sudan. This survey aimed to investigate the prevalence of elevated blood pressure/hypertension and associated factors among adolescents in Gadarif City, Sudan.

METHODS

A community-based cross-sectional survey was conducted during a three-month period (August to October 2023) in Gadarif City, Eastern Sudan. A face-to-face interview questionnaire was used to collect sociodemographic information. Adolescents' anthropometric (weight and height) measurements were taken, and blood pressure was measured. Multivariate binary and linear regression analyses were performed to analyze the data.

RESULTS

A total of 384 adolescents (178 [46.4%] boys and 206 [53.6%] girls) were included in the study. The median (interquartile range, IQR) of the age was 14.0 (12.1-16.1) years, and that of the body mass index (BMI) was 16.9 (15.2-20.0) kg/m2. Thirty-four (8.9%) adolescents had hypertension/elevated blood pressure (≥95th percentile). After adjusting for confounders, multivariable binary regression analysis showed that age (adjusted odds ratio [AOR], 1.20; 95% confidence interval [CI], 1.03-1.42) and BMI (AOR, 1.12; 95% CI, 1.04-1.20) were associated with hypertension.

CONCLUSION

Approximately one in ten adolescents in Eastern Sudan was hypertensive. Adolescents with higher age and BMI were at higher risk for hypertension. Maintaining a healthy BMI during adolescence is recommended to promote adolescents' health.

Relationship between socioeconomic status and hypertension incidence among adults in southwest China: a population-based cohort study

PURPOSE

To investigate the correlation between socioeconomic status (SES) and the incidence of hypertension among adults aged 18 or above in southwest China.

METHODS

A multistage proportional stratified cluster sampling method was employed to recruited 9280 adult residents from 12 counties in southwest China, with all participants in the cohort tracked from 2016 to 2020. The questionnaire survey gathered information on demographics, lifestyle habits, and household income. The physical exam recorded height, weight, and blood pressure. Biochemical tests measured cholesterol levels. The chi-square test was employed to assess the statistical differences among categorical variables, while the Cox proportional hazards regression model was applied to evaluate the association between socioeconomic status (SES) and the incidence of hypertension.

RESULTS

The finally effective sample size for the cohort study was 3546 participants, after excluding 5734 people who met the exclusion criteria. Adults in the highest household income group had a significantly lower risk of hypertension compared to those in the lowest income group (HR = 0.636, 95% CI: 0.478-0.845). Besides, when compared to individuals in the illiterate population, the risk of hypertension among adults with elementary school, junior high school, senior high school and associate degree educational level decreased respectively by 34.4% (HR = 0.656, 95%CI: 0.533-0.807), 44.9% (HR = 0.551, 95%CI: 0.436-0.697), 44.9% (HR = 0.551, 95%CI: 0.405-0.750), 46.1% (HR = 0.539, 95%CI: 0. 340-0.854). After conducting a thorough analysis of socioeconomic status, compared with individuals with a score of 6 or less, the risk of hypertension in participants with scores of 8, 10, 11, 12, and greater than 12 decreased respectively by 23.9% (HR = 0.761, 95%CI: 0.598-0.969), 29.7% (HR = 0.703, 95%CI: 0.538-0.919), 34.0% (HR = 0.660, 95%CI: 0.492-0.885), 34.3% (HR = 0.657, 95%CI: 0.447-0.967), 43.9% (HR = 0.561, 95%CI: 0.409-0.769).

CONCLUSION

The findings indicate a negative correlation between socioeconomic status and hypertension incidence among adults in southwest China, suggesting that individuals with higher socioeconomic status are less likely to develop hypertension.

Association between body roundness index and prevalence of kidney stone in the U.S: a study based on the NHANES database

OBJECTIVE

This study aimed to evaluate the potential association between the body roundness index (BRI) and kidney stone prevalence in adults in the United States.

METHODS

A cohort of participants from the National Health and Nutrition Examination Survey (NHANES) database spanning 2007-2018 were gathered for analysis. Logistic regression analyses, subgroup assessments, and calculations were employed to examine the potential link between BRI and kidney stone prevalence.

RESULTS

The study included 30,990 participants aged > 20 years, of which 2,891 declared a kidney stone history. After modulating all relevant confounding factors, each unit increase in the BRI was linked to a 65% increase in kidney stone prevalence (OR = 1.65, 95% CI: 1.47, 1.85). Sensitivity analyses conducted by categorizing the BRI into three groups revealed a 59% increase in kidney stone prevalence in the highest tertile BRI group compared to the lowest one (OR = 1.59, 95% CI: 1.42, 1.79). Furthermore, dose-response curves depicted a positive near-linear correlation between the BRI and the risk of kidney stone prevalence.

CONCLUSION

These findings suggest a clinically noteworthy positive correlation between higher BRI values and kidney stone prevalence among the studied US adult population. However, it is essential to acknowledge that the observed relationship does not establish a causal link.

Investigating the Relationship Between Hypertension and Obesity in Schoolchildren From Lower-Middle Socioeconomic Strata in Urban Mumbai

Background In light of escalating rates of childhood obesity, understanding the gender-specific correlation between body mass index (BMI) and hypertension has become crucial for effective public health interventions. This study investigates the interplay between BMI and hypertension among school-aged children, with a particular emphasis on gender stratification to identify distinct trends. Methodology A cross-sectional study was conducted with a diverse sample of 702 schoolchildren aged 5-16 years from a lower-middle-income school in urban Mumbai. This cohort consisted of 491 boys and 211 girls within the gender subset. BMI was calculated using height and weight measurements, while blood pressure readings determined hypertension prevalence. The children were categorized based on the Indian Academy of Pediatrics (IAP) growth chart BMI calculations and blood pressure percentiles. SPSS Statistics version 23 (IBM Corp., Armonk, NY, USA) was used for data analysis. Data were analyzed using the chi-square test, with p-values <0.05 deemed significant. Results The overall prevalence of overweight was 16.52%, with 15.89% in boys and 18.10% in girls, revealing no significant gender difference (p = 0.487). In terms of obesity, the overall prevalence was 10.83%, with 10.99% in boys and 10.34% in girls, revealing no significant gender difference (p = 0.823). The prevalence of pre-hypertension was 7%, exhibiting a significantly higher prevalence in high BMI males (overweight and obese) versus non-high BMI males (normal and underweight) (p < 0.001); however, no such difference was observed in females (p = 0.289). The prevalence of hypertension was 15.95% with a significantly higher prevalence in high BMI males (overweight and obese) versus non-high BMI males (normal and underweight) (p < 0.001) and high BMI females (overweight and obese) versus non-high BMI females (normal and underweight) (p < 0.001). Hypertension was significantly higher in children with high BMI (overweight and obese) compared to their non-high BMI (normal and underweight) counterparts. Conclusions In lower-middle socioeconomic strata schoolchildren in urban Mumbai, the prevalence of obesity and hypertension was alarmingly high, attributed to shifting lifestyles and unhealthy dietary habits. Hypertension rates were notably elevated among overweight and obese individuals compared to normal and underweight individuals. More than a third of both boys and girls with obesity were diagnosed with hypertension, emphasizing a concerning surge in hypertension cases among children. Prioritizing age-specific blood pressure assessments can facilitate early identification and timely interventions.

Relationship between gout, hyperuricemia, and obesity-does central obesity play a significant role?-a study based on the NHANES database

BACKGROUND

Our objective was to evaluate how various measures of obesity, such as body mass index(BMI), body roundness index(BRI), and weigh adjusted waist index(WWI), influence urate levels, prevalence of gout and to compare the disparities among these obesity indicators.

METHODS

By analyzing the 2001-2018 National Health and Nutrition Examination Survey (NHANES), we assessed the relationship between BMI, WWI, and BRI indices and urate levels, hyperuricemia, and the prevalence of gout. Smoothed curve fitting was used to determine whether there was a nonlinear relationship between BMI,WWI, and BRI indices and urate levels, hyperuricemia, and the prevalence of gout, and threshold effects analysis was used to test this relationship. We also used ROC curves to determine the diagnostic efficacy of BMI, WWI, and BRI on the prevalence of hyperuricemia and gout.

RESULTS

The study incorporated a total of 29,310 participants aged over 20 years, out of which 14,268 were male. Following the adjustment for the pertinent confounding factors, it was observed that higher levels of BMI, WWI, and BRI were significantly associated with a gradual and dose-dependent increase in urate levels. In the sensitivity analysis, each unit increment in BMI, WWI, and BRI levels exhibited an 8%, 72%, and 26% respective elevation in the risk of hyperuricemia, as well as a 5%, 31%, and 15% respective increase in the risk of gout. Dose-response curves provided evidence of a linear positive correlation between BMI, WWI, BRI, and urate levels, as well as the prevalence of hyperuricemia and gout. Based on the response from the ROC curve, overall, the diagnostic efficacy of BRI for hyperuricemia and gout surpasses that of BMI.

CONCLUSION

The central obesity indices WWI and BRI levels are superior to BMI in detecting the prevalence of urate levels, hyperuricemia, and gout, and although a clear causal relationship has not yet been established, it is important to recognize the impact of central obesity on uric acid levels and to give it due attention.

The Association Between Body Mass Index and Parental History of Hypertension Among Young Indian Adults

BACKGROUND

Hypertension is a disease of multifactorial etiology. Individuals with parental history of hypertension (PHH) have also been observed to be at an increased risk of developing hypertension in their adult life. However, there is a dearth of studies among youth. Obesity is one of the risk factors, and studies conducted among adults of all age groups have observed that there is a highly significant correlation between hypertension and body mass index (BMI). Hence, the association between the two factors, viz., parental history of hypertension and BMI, among the young Indian male and female population was analyzed in this study.

METHOD

This cross-sectional study conducted in Central India comprised 100 young adults between 18 and 25 years of age. On the basis of parental history of hypertension, the subjects were divided into two groups: group 1 comprised youth with parental history of hypertension and group 2 comprised youth without parental history of hypertension, involving 32 and 68 subjects in each of these groups, respectively. Anthropometric measurements were done using standard methods, and BMI was calculated. Statistical analysis was done using Epi Info software.

RESULTS

The study subjects in both groups were comparable in age. The mean age of the study participants was 19.32 years and 19.45 years in group 1 and group 2, respectively. The study did not find any association between BMI and parental history of hypertension.

CONCLUSION

The association between parental history of hypertension and BMI, the non-modifiable and modifiable independent risk factors, respectively, needs to be further explored in light of the iceberg phenomenon, multifactorial causation, and natural history of disease. It is worth mentioning that parental history of hypertension and other risk factors should be considered even if the BMI is normal as per Asian Indian cutoff levels.

The Prevalence of Elevated Blood Pressure and Its Association With Obesity in Children Aged 6-13 Years in Rural India: A Cross-Sectional Study

Introduction Globally, hypertension is one of the major risk factors for cardiovascular disease. Childhood hypertension is one of the emerging conditions due to the increase in the prevalence of obesity in children in developing countries. An increase in blood pressure (BP) can be classified as secondary hypertension if it is caused by an underlying disease process or as primary hypertension if there is no identifiable cause. Primary hypertension during childhood often tracks into adulthood. The prevalence of primary hypertension, mostly in older school-aged children and adolescents, has increased in parallel with an obesity epidemic. Materials and methods This cross-sectional descriptive study was taken in different schools in the rural areas of Trichy District, Tamil Nadu, for a period of six months from July 2022 to December 2022; the study was done in children between six and 13 years. Anthropometry was taken, and blood pressure was measured using an appropriate-size BP cuff and standardized sphygmomanometer. Three values were taken at an interval for a minimum of five minutes, and the mean of the three values was calculated. Blood pressure percentiles were adopted from the American Academy of Pediatrics (AAP) 2017 guidelines for childhood hypertension. Results Out of 878 students, 49 (5.58%) students had abnormal BP, of which 28 (3.19%) students were categorized into elevated BP and 21 (2.39%) students had hypertension both in stages 1 and 2. Abnormal blood pressure was equally distributed in both males and females. More students were from the age group between 12 and 13 years (chi-square value: 58.469, P=0.001), which shows that as age increases, the prevalence of hypertension increases. The mean weight was around 31.97 kg, and the mean height was 135.34 cm. In this study, we found that 223 (25%) students were overweight and 53 (6.03%) students were obese. The prevalence of hypertension was 15.09% in the obese category and 1.35% in the overweight category (chi-square value: 83.712, P=0.000). Conclusion Due to limited data available on childhood hypertension based on the American Academy of Pediatrics (AAP) 2017 guidelines, this study highlights the AAP 2017 guidelines for early diagnosis of elevated BP and various stages of hypertension in children, and also, the need for early detection of obesity is essential for the implementation of a healthy lifestyle. This study helps create awareness among parents regarding the rise of obesity and hypertension in children in rural populations of India.
