RESUMO
Dengue disease encompasses various clinical manifestations including dengue fever (DF) and dengue hemorrhagic fever (DHF). In this article, we aimed to systematically review and analyze the association between different blood groups and severity of dengue. We searched nine databases for eligible papers reporting prevalence, distribution, and frequency of blood group type among dengue patients. Network meta-analysis using R software was used to analyze the data. Of a total of 63 reports screened, we included 10 studies with total sample size 1977 patients (1382 DF and 595 DHF). Blood group O was found to have the worst outcome with the highest risk of developing DF (P-score = 0.01) followed by group B (P-score = 0.34), group A (P-score = 0.64), and group AB (P-score = 1), respectively. Blood group O also had the worst outcome with highest risk of developing DHF (P-score = 0.1) followed by group B (P-score = 0.29), group A (P-score = 0.61), and group AB (P-score = 1), respectively. There was a significant increase (P-value <.001) in the overall odds risk of dengue infection among patients with Rhesus-positive blood groups [OR = 540.03; (95% CI = 151.48-1925.18)]. However, there was no significant difference in the odds risk of DF when compared to DHF according to Rhesus status (P-value = .954). This study identified the O blood group as a potential risk factor in predicting clinical severity in dengue patients which may be helpful in evaluating patients for their likely need for critical care.

PURPOSE: Men with Gleason score 9-10 prostate cancer have worse outcomes compared to those with Gleason 8 disease. Upfront treatments remain controversial for these patients. Using the Surveillance, Epidemiology, and End Results (SEER) database, we evaluated the impact of initial treatment with external beam radiation therapy (EBRT), external beam radiation therapy with brachytherapy (EBRT + BT), or surgery on prostate cancer-specific mortality (PCSM) and overall mortality (OM) in Gleason 9-10 disease. METHODS: The SEER database was queried for men diagnosed with biopsy Gleason 9-10 prostate cancer from 2005 to 2014. Gathered data included demographic, pathologic, therapy received, and survival outcomes. Kaplan-Meier survival curves and crude and multivariate analyses were generated for initial therapy with EBRT, EBRT + BT, or surgery. RESULTS: A total of 7877 men were included, 4465 (56.7%) who underwent upfront treatment with EBRT alone, 623 (7.9%) with EBRT + BT, and 2789 (35.4%) with surgery. The 7 year PCSM rates were 29.2, 15.0, and 14.6% for EBRT, EBRT + BT, and surgery respectively (p < 0.001). The 7 year OM rates were 43.8, 27.2, and 20.0% for EBRT, EBRT + BT, and surgery, respectively (p < 0.001).When controlling for age, year of diagnosis, Gleason score, clinical T stage, and PSA level on multivariate analysis, EBRT had greater PCSM and OM than surgery (HR 0.41, 95% CI 0.28-0.61, p < 0.001 and HR 0.44, 95% CI 0.34-0.57, p < 0.001 respectively), but the mortality differences was not statistically significant between EBRT and EBRT + BT. CONCLUSION: Among men with localized Gleason 9-10 disease, surgery was associated with statistically significant improved survival outcomes compared to EBRT alone.

This cross-sectional study investigated the factors associated with hypertension among Nepalese adults aged 18 years or above using data from the Nepal Demographic and Health Survey 2016. Prevalence ratios (PRs) and odds ratios (ORs) were obtained using log-binomial regression and logistic regression, respectively. Initially, unadjusted PRs and ORs were obtained. The variables that yielded a significance level below 0.2 in unadjusted analyses were included in the multivariable analysis. The overall prevalence of hypertension among the 13,393 participants (58% male and 61.2% urban) was 21.1% (n = 2827). In the adjusted analysis, those aged 30-49 years (adjusted PR [APR]: 3.1, 95% Confidence Interval (CI): 2.6, 3.7; adjusted OR [AOR]: 3.6, 95% CI: 2.9, 4.5), 50-69 years (APR: 5.3, 95% CI: 4.4, 6.6; AOR: 8.2, 95% CI: 6.4, 10.4) and ≥70 years (APR: 7.3, 95% CI: 5.8, 9.2; AOR: 13.6, 95% CI: 10.1, 18.3) were more likely to be hypertensive than younger participants aged 18-29 years. Males (APR: 1.3, 95% CI: 1.2, 1.4; AOR: 1.5, 95% CI: 1.3, 1.7), overweight/obese participants (APR: 1.8, 95% CI: 1.7, 2.0; AOR: 2.4, 95% CI: 2.2, 2.8) and those in the richest wealth quintile (APR: 1.3, 95% CI: 1.1, 1.5; AOR: 1.5, 95% CI: 1.1, 1.9) had higher prevalences and odds of hypertension than their female, normal weight/underweight and poorest wealth quintile counterparts, respectively. Those residing in Province 4 (APR: 1.2, 95% CI: 1.0, 1.5; AOR: 1.4, 95% CI: 1.1, 1.8) and Province 5 (APR: 1.2, 95% CI: 1.0, 1.4; AOR: 1.3, 95% CI: 1.1, 1.7) were more likely to be hypertensive than those residing in Province 1. The point estimate was inflated more in magnitude by ORs than by PRs, but the direction of association remained the same. Public health programmes in Nepal aimed at preventing hypertension should raise awareness among the elderly, males, individuals in the richest wealth quintile and the residents of Provinces 4 and 5.

INTRODUCTION: Childhood hypertension is associated with higher risks of cardiovascular disease during adulthood. This study estimated the prevalence of hypertension and high blood pressure among children aged 8 to 17 years in the United States per the 2017 American Academy of Pediatrics (AAP) guideline and compared that with the 2004 National Institutes of Health/National Heart, Lung, and Blood Institute (NIH/NHLBI) guideline's prevalence estimate during 2005-2008 and 2013-2016. METHODS: This cross-sectional study analyzed the National Health and Nutrition Examination Survey data. High blood pressure included hypertension and elevated blood pressure (per the 2017 AAP guideline)/prehypertension (per the 2004 NIH/NHLBI guideline). RESULTS: The analysis included 3,633 children in 2005-2008 and 3,471 children in 2013-2016. Per the 2004 NIH/NHLBI guideline, 3.1% (95% confidence interval [CI], 2.3%-4.3%) had hypertension in 2005-2008 and 1.9% (95% CI, 1.4%-2.6%) had hypertension in 2013-2016. Per the 2017 AAP guideline, prevalence was 5.7% (95% CI, 4.6%-7.1%) in 2005-2008 and 3.5% (95% CI, 2.7%-4.5%) in 2013-2016. About 2.5% (95% CI, 2.0%-3.1%) children in 2005-2008 and 1.5% (95% CI, 0.9%-2.0%) children in 2013-2016 were reclassified as hypertensive. We observed a similar change in prevalence for high blood pressure after application of the new guideline. The prevalence of high blood pressure also declined from 2005-2008 to 2013-2016 per both guidelines. CONCLUSION: Although the new guideline would reclassify a small proportion of children as having hypertension or high blood pressure, the prevalence declined from 2005-2008 to 2013-2016.

BACKGROUND: Reducing death due to neonatal sepsis is a global health priority, however there are limited tools to facilitate early recognition and treatment. We hypothesized that measuring circulating biomarkers of endothelial function and integrity (i.e. Angiopoietin-Tie2 axis) would identify young infants with sepsis and predict their clinical outcome. METHODS: We conducted a matched case-control (1:3) study of 98 young infants aged 0-59 days of life presenting to a referral hospital in Bangladesh with suspected sepsis. Plasma levels of Ang-1, Ang-2, sICAM-1, and sVCAM-1 concentrations were measured at admission. The primary outcome was mortality (n = 18); the secondary outcome was bacteremia (n = 10). RESULTS: Ang-2 concentrations at presentation were higher among infants who subsequently died of sepsis compared to survivors (aOR 2.50, p = 0.024). Compared to surviving control infants, the Ang-2:Ang-1 ratio was higher among infants who died (aOR 2.29, p = 0.016) and in infants with bacteremia (aOR 5.72, p = 0.041), and there was an increased odds of death across Ang-2:Ang-1 ratio tertiles (aOR 4.82, p = 0.013). CONCLUSIONS: This study provides new evidence linking the Angiopoietin-Tie2 pathway with mortality and bacteremia in young infants with suspected sepsis. If validated in additional studies, markers of the angiopoietin-Tie2 axis may have clinical utility in risk stratification of infants with suspected sepsis.

We investigated the feasibility of an interactive voice response (IVR) survey in Tanzania and compared its prevalence estimates for tobacco use to the estimates of the 'Global Adult Tobacco Survey (GATS) 2018'. IVR participants were enrolled by random digit dialing. Quota sampling was employed to achieve the required sample sizes of age-sex strata: sex (male/female) and age (18-29-, 30-44-, 45-59-, and ≥60-year-olds). GATS was a nationally representative survey and used a multistage stratified cluster sampling design. The IVR sample's weights were generated using the inverse proportional weighting (IPW) method with a logit model and the standard age-sex distribution of Tanzania. The IVR and GATS had 2362 and 4555 participants, respectively. Compared to GATS, the unweighted IVR sample had a higher proportion of males (58.7 % vs. 43.2 %), educated people (secondary/above education: 43.3 % vs. 21.1 %), and urban residents (56.5 % vs. 40 %). The weighted prevalence (95 % confidence interval (CI)) of current smoking was 4.99 % (4.11-6.04), 5.22 % (4.36-6.24), and 7.36 % (6.51-8.31) among IVR (IPW), IVR (age-sex standard), and GATS samples, respectively; the weighted prevalence (95 % CI) of smokeless tobacco use was similar: 3.54 % (2.73-4.57), 3.58 % (2.80-4.56), and 2.43 % (1.98-2.98), respectively. Most differences in point estimates for tobacco indicators were small (<2%). Overall, the odds of tobacco smoking indicators were lower in IVR than in GATS; however, the odds of smokeless tobacco use were reversed. Although we found under-/over-estimation of the prevalence of tobacco use in IVR than GATS, the estimates were close. Further research is required to increase the representativeness of IVR.
RESUMO
Objective: Evaluate feasibility and impact of a multimodal integrative therapeutic intervention in patients presenting with chronic symptoms attributed to a postinfectious syndrome. Design: This was a prospective longitudinal single-center pilot study conducted from January 2019 to December 2020. Setting/Location: University of Maryland Lyme Program, Baltimore Maryland. Subjects: Persons presenting for Lyme evaluation for symptoms attributed to Lyme disease. Interventions: Participants attended two 1-h individual instructional sessions consisting of Ayurveda-based dietary intervention and breath-coordinated mind-body practice to be used for home practice. Outcome measures: Standard measures of impact were obtained at baseline, 1, 3, 6, and 12 months using the following validated survey instruments: Perceived Stress Scale (PSS), PROMIS Global Health v1.2 (GH), and PROMIS 29 v2.0 survey. Results: From 216 patients presenting for Lyme evaluation, 19 participants enrolled with 84% completing the study (N = 16). Baseline PROMIS GH scores consisting of general Physical Health (GPH) and general Mental Health (GMH) scores were lower in the study population than in the general U.S. population. PROMIS 29 scores were higher for fatigue, anxiety, and pain than those in the general U.S. population. Over 12-month period, improvement in both the GPH and GMH was 6.09 (confidence interval [95% CI] = 2.71-9.46; p < 0.001) and 4.65 (95% CI = 1.50-7.80; p = 0.004), respectively. PROMIS 29 scores showed the greatest improvement in fatigue at -7.91 (95% CI = -12.34 to -3.48; p < 0.001), pain interference -5.08 (95% CI = -9.20 to -0.96; p = 0.016), and ability to participate in social roles and activities 7.48 (95% CI = 3.21-11.75; p = 0.001) and least with depression -1.82 (95% CI = -4.74 to 1.10; p = 0.223). Employment status had significant effects on almost all outcome scores. Postinfectious state was associated with improvement in anxiety and PSS scores. Conclusions: A multimodal Ayurvedic and breath-coordinated mind-body therapeutic intervention is feasible and a potential nonpharmacologic therapeutic option for persons presenting with pain, stress, fatigue, physical dysfunction, and sleep disturbance attributed to a postinfectious syndrome. Further research is needed to determine efficacy in this population and in other groups with similar symptom complexes due to postinfectious syndromes.
RESUMO
We aimed to calculate the sex-specific prevalence of psychological distress and unhealthy eating habits among adolescents across countries and regions, and to explore their potential associations. We used data from the Global School-Based Health Survey (GSHS) for 61 countries. Psychological distress was defined based on the existence of ≥ 2 factors from the following: loneliness, anxiety, suicide ideation, suicide planning, and suicide attempt. Four unhealthy dietary behaviours were examined: inadequate fruit intake, inadequate vegetable intake, daily consumption of soft drinks, and weekly fast-food consumption. We used random-effects meta-analysis to estimate the overall and regional pooled prevalence. Mixed-effect multilevel logistic regressions were used to estimate adjusted odds ratios (aORs) of unhealthy dietary behaviours in relation to psychological distress. Among 222,401 school-going adolescents (53.3% girls), the prevalence of psychological distress was 17.9%, with girls reporting higher than boys (20.8% vs. 14.9%). Adolescents in the African region reported the highest prevalence (22.5%), while those in the South-East Asia region reported the lowest (11.3%). The prevalence of inadequate fruit intake, inadequate vegetable intake, daily soft drink consumption, and weekly fast-food consumption was 37.0%, 28.5%, 50.0%, and 57.4% respectively. Psychological distress was associated with inadequate fruit intake (pooled aOR = 1.19, 95% CI 1.17-1.23), inadequate vegetable intake (pooled OR = 1.19, 1.16-1.22), daily consumption of soft drinks (pooled aOR = 1.14, 1.12-1.17), and weekly consumption of fast food (pooled aOR = 1.12, 1.09-1.15). Our findings indicate a substantial variance in the burden of psychological distress and unhealthy dietary behaviours across different regions. Adolescents experiencing psychological distress were more likely to have unhealthy dietary habits.

INTRODUCTION: Automated mobile phone surveys (MPS) can be used to collect public health data of various types to inform health policy and programs globally. One challenge in administering MPS is identification of an appropriate and effective participant consent process. This study investigated the impact of different survey consent approaches on participant disposition (response characteristics and understanding of the purpose of the survey) within the context of an MPS that measured noncommunicable disease (NCD) risk factors across Colombia and Uganda. METHODS: Participants were randomized to one of five consent approaches, with consent modules varying by the consent disclosure and mode of authorization. The control arm consisted of a standard consent disclosure and a combined opt-in/opt-out mode of authorization. The other four arms consist of a modified consent disclosure and one of four different forms of authorization (i.e., opt-in, opt-out, combined opt-in/opt-out, or implied). Data related to respondent disposition and respondent understanding of the survey purpose were analyzed. RESULTS: Among 1889 completed surveys in Colombia, differences in contact, response, refusal, and cooperation rates by study arms were found. About 68% of respondents correctly identified the survey purpose, with no significant difference by study arm. Participants reporting higher levels of education and urban residency were more likely to identify the purpose correctly. Participants were also more likely to accurately identify the survey purpose after completing several survey modules, compared to immediately following the consent disclosure (78.8% vs 54.2% correct, p<0.001). In Uganda, 1890 completed surveys were collected. Though there were differences in contact, refusal, and cooperation rates by study arm, response rates were similar across arms. About 37% of respondents identified the survey purpose correctly, with no difference by arm. Those with higher levels of education and who completed the survey in English were able to more accurately identify the survey purpose. Again, participants were more likely to accurately identify the purpose of the survey after completing several NCD modules, compared to immediately following the consent module (42.0% vs 32.2% correct, p = 0.013). CONCLUSION: This study contributes to the limited available evidence regarding consent procedures for automated MPS. Future studies should develop and trial additional interventions to enhance consent for automated public health surveys, and measure other dimensions of participant engagement and understanding.

BACKGROUND: The prevalence of hypertension is increasing in Bangladesh, however, few recent studies investigated the proportion of people and factors associated with prevalence, awareness, and control of this condition in this country. This study investigated these among Bangladeshi adults. METHODS: Using Bangladesh Demographic and Health Survey 2017-18 data, a cross-sectional study was conducted. Multilevel logistic regression analysis was employed after descriptive analysis and prevalence estimation. RESULTS: Among 12,926 persons (mean age: 40 years, 57% women), the prevalence of hypertension was 27.4% (n = 3551), it was 28.4 and 26.2% among females and males, respectively. Among hypertensive people, about 42.4% (n = 1508) people were aware of having it, 48.7% among females and 33.5% among males. Of the 1313 people who were taking antihypertensive medication, only 33.8% (n = 443) had controlled hypertension, 34.7 and 31.7% among females and males, respectively. Among the studied factors associated with hypertension, people with older age, female gender, overweight/obesity, diabetes, richer wealth quintiles, and residence in some administrative divisions had higher odds of hypertension (p < 0.05). However, the odds of awareness was lower among younger people, males, and people without overweight/obesity, diabetes, or richer wealth quintiles. Odds of controlled hypertension was also lower among people with older age and higher among college-educated people. CONCLUSION: This study identified several important factors associated with prevalence, awareness, and control of hypertension. It is important to address these factors with nationwide prevention and control programs.
RESUMO
BACKGROUND: Previous studies that investigated association of height with prevalence and control of hypertension found mixed results. This cross-sectional study explored these associations among US adults (≥20 years). METHODS: The National Health and Nutrition Examination Survey (NHANES) 2007-18 data was analyzed. Height was measured in meters and was converted into centimeters (cm) and was further divided into quartiles: Q1 (135.3-159.2 cm), Q2 (159.3-166.2 cm), Q3 (166.3-173.6 cm), Q4 (173.7-204.5 cm). Hypertension definition of the '2017 American College of Cardiology/American Heart Association Guideline' was used. Logistic regression analyses were conducted to find out the association between the dependent variable and the covariates. Linear regression analyses were conducted to find out the association of height with systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP), and the covariates among the individuals who were not taking any antihypertensive drugs. Crude odds ratio, adjusted odds ratio (AOR), and adjusted beta-coefficient (for linear regression) with 95% confidence interval (CI) were reported. The following covariates were included: age, gender, race/ethnicity, family income, education level, cholesterol level, high-density lipoprotein level, chronic kidney disease status, diabetes status, smoker, aerobic leisure-time physical activity, and survey period. Sample weight of NHANES was adjusted. RESULTS: Among the 21,935 participants (47.1% males), the prevalence of hypertension was 46.1%. Among 6154 participants taking medication (43.0% males), 57.2% had uncontrolled hypertension. In the final logistic regression analyses, participants in Q2 height quartile had 20% lower odds of being hypertensive compared to those in Q4 height quartile (AOR: 0.8; 95% CI: 0.7,1.0). Other height categories did not reveal any significant association. Compared to Q4 height category, Q1 (AOR: 1.7; 95% CI: 1.2,2.3), Q2 (AOR: 1.4; 95% CI: 1.1,1.8), and Q3 (AOR: 1.3; 95% CI: 1.1,1.6) height categories had higher odds of uncontrolled hypertension. PP was inversely associated and DBP was positively associated with height. CONCLUSIONS: Although height was not associated with prevalence of hypertension, it had inverse association with uncontrolled hypertension. It was also significantly associated with DBP and PP among the individuals with untreated hypertension.
RESUMO
We investigated the prevalence of hypertension in Ghana using the 2017 American College of Cardiology/American Heart Association (ACC/AHA) criteria and compared with prevalence estimates using the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC7) criteria. Among 13,220 Ghanaians aged 15-49 years, the prevalence of hypertension was 30.4% (95% CI: 29.3-31.6) based on the 2017 ACC/AHA guideline compared with 12.8% (95% CI: 12.0-13.6) when using the JNC7 guideline. The overall increase in prevalence was 17.6% (95% CI: 16.8-18.6). The increment in prevalence was 19.0% (95% CI: 17.5-20.7) among men and 17.7% (95% CI: 16.1-18.2) among women. People aged 40-49 years had the highest prevalence (51.1%; 95% CI: 49.0-53.3). We used multiple logistic regressions to obtain odds ratios. Urban dwelling, tertiary education, or being in higher wealth status was significantly associated with the odds of hypertension. The 2017 ACC/AHA guideline resulted in a significant increase in the prevalence of hypertension in Ghana. Scaling up of existing prevention and control strategies for hypertension such as health education through already established community health implementation and planning programs as well as improved screening and diagnostic protocols for hypertension should be prioritized.

OBJECTIVE: To estimate the prevalence and determinants of hypertension in India based on a new definition by the 2017 American College of Cardiology/American Heart Association (2017 ACC/AHA) Guideline for the Prevention, Detection, Evaluation and Management of High Blood Pressure in Adults, and compare prevalence estimates with those of the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC7). METHODS: We used the National Family Health Survey (NFHS-4) conducted in India (n = 212,007). We accounted for the sampling strategy by applying survey weights. RESULTS: Prevalence of hypertension among Indians aged 15-49 years was 40.6% (95% confidence interval [CI]: 40.3-41.0) and 13.0% (95% CI: 12.8-13.2) based on 2017 ACC/AHA and JNC7 guidelines respectively. The overall absolute increase in prevalence was 27.6% (95% CI:27.3-27.9). The absolute changes in crude prevalence of hypertension between the JNC7 and 2017 ACC/AHA guidelines for men and women were 31.4% (95% CI: 30.9-31.9) and 23.7% (95% CI: 23.5-23.9), respectively. As per both guidelines, the overall prevalence was significantly higher among older people, age, male sex, overweight/obesity, higher wealth status, and urban residence. CONCLUSION: Applying the 2017 ACC/AHA guideline to the Indian population led to a significantâ¯increase in the proportion of Indians with hypertension. There is also socioeconomic differences in the prevalence of hypertension as per both guidelines. Implementation and expansion of public health efforts for prevention and control strategies for hypertension is warranted.

OBJECTIVES: This study aimed to investigate the differences in prevalence and factors influencing underweight and overweight/obesity stratified by region of residence among women of reproductive age in Bangladesh. DESIGN: Secondary analysis of cross-sectional nationwide data. SETTING: This study used Bangladesh Demographic and Health Survey 2014 data. PARTICIPANTS: A weighted sample of 16 478 women of reproductive age (15-49 years) were included in the analysis. PRIMARY AND SECONDARY OUTCOME MEASURES: Using the Asian-specific cut-off for body mass index, the primary outcome of this study was categorised as: underweight (<18.5 kg/m2), normal weight (18.5 to <23.0) kg/m2 and overweight/obese (≥23.0 kg/m2) stratified according to rural-urban residence. RESULTS: More than half of urban women (53%, n=2493) and one-third of rural women (33%, n=3968) were found to be overweight/obese. Around one-fifth of rural women (21%, n=2490) and almost one in eight urban women (12%, n=571) were reported as underweight. In the final multivariable analyses, increasing age, higher educational status and higher order wealth quintile, each had a significant positive association with being overweight/obese and an inverse association with being underweight. Urban unmarried women had lower odds of being overweight/obese compared with their married counterparts. Rural women who used contraceptives had significantly decreased odds (adjusted OR (AOR) 0.8, 95% CI 0.7 to 0.9) of being underweight compared with contraceptive non-users; no such association was noted in urban women. Women from Sylhet division in both urban (AOR 1.7, 95% CI 1.2 to 2.5) and rural regions (AOR 1.5, 95% CI 1.2 to 1.8) had increased odds of being underweight compared with women in Barisal division. CONCLUSIONS: This study found association of multiple factors with both overweight/obesity and underweight among Bangladeshi women of reproductive age. Public health programmes in Bangladesh aiming to prevent the double burden of malnutrition should focus these factors through comprehensive public awareness and cost-effective operational health interventions.

OBJECTIVE: There is a little published data on prevalence and determinants of underweight, overweight and obesity among adults in Nepal. This study analysed the cross-sectional Nepal Demographic and Health Survey (NDHS) 2016 to obtain these using the World Health Organization (WHO) and Asian-specific cutoffs of body mass index (BMI). METHODS: The 2016 NDHS used a multistage cluster-sampling design to obtain data on major health indicators in Nepal. The BMI cutoffs for underweight was <18.5kg/m2. The BMI cutoffs for overweight/obesity as per the Asian and WHO classifications were ≥23, and ≥25kg/m2, respectively. After reporting the prevalence according to sex and background characteristics, multilevel logistic regression was conducted to estimate odds ratios. SUBJECTS: This analysis included 12,652 adults (5283 males and 7369 females) with a median age of 40 years (interquartile range [IQR]: 28-54). RESULTS: The overall median BMI was 21.5kg/m2 (IQR:19.3-24.3). The overall prevalence of underweight was 16.7% (15.1% among males and 17.1% among females). The Asian-specific BMI cutoffs found the prevalence of overweight and obesity as 26.4% (27.4% among males and 25.6% among females) and 11.0% (7.7% among males and 13.3% among females), respectively. The WHO-recommended BMI cutoffs found 18.2% people overweight (16.7% among males and 19.3% among females) and 4.3% (2.5% among males and 5.6% among females) people obese. The prevalence and odds of extreme body weight categories (i.e., underweight, overweight and obesity) varied according to age, sex, education level, household wealth status, place, ecological zone and provinces of residence as per both recommended cutoffs. Overall, higher education level and wealth status were positively associated with overweight/obesity and inversely associated with underweight as per both cutoffs. CONCLUSION: A large proportion Nepalese adults have either underweight, overweight or obesity, and could be at a greater risk of mortality and morbidity due to these extreme body weight categories. It is essential to address the factors or characteristics that are associated with the higher prevalence and likelihood of these extreme body weight categories to reduce the overall burden of underweight and overweight/obesity in Nepal.

The 2017 American College of Cardiology/American Heart Association (ACC/AHA) Guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults recommends reduced systolic/diastolic blood pressure (SBP/DBP) cutoffs to define hypertension (i.e., by changing these from ≥140/90 to ≥130/80â¯mmHg), including new recommendations about indications and goals of antihypertensive treatment. This study reported the differences in age-adjusted prevalence and treatment status of hypertension according to race among US adults per the 2017 ACC/AHA guideline. The National Health and Nutrition Examination Survey 2011-16 data was analyzed. The main outcomes were age-adjusted prevalence and treatment status of hypertension among adults aged ≥20â¯years. After prevalence estimation, other proportions were obtained. The analysis included 16,103 adults (mean age: 47.6â¯years, 51.8% women). The age-adjusted proportions of adults with hypertension (59.0%, 95% confidence interval [CI]: 57.4%-60.6%), treatment-eligible for hypertension (49.3%, 95% CI: 47.7%-50.8%), and unmet treatment goals (63.8%, 95% CI: 60.0%-67.5%) among the treated were highest among non-Hispanic blacks. A large proportion of Mexican-Americans (46.5%, 95% CI: 42.0%-51.0%) and people of other races/ethnicities (49.3%, 95% CI: 45.5%-53.0%) were not receiving treatment despite having indication. Non-Hispanic blacks also had the highest prevalence of stage 2 hypertension. Among all races, prevalence, treatment-eligibility, and unmet treatment goals were higher among people with older age, male gender, diabetes, higher body weight, and higher cardiovascular disease risk while the majority of younger, lower/normal body weight, or non-diabetic people were untreated despite being eligible for treatment. The prevalence, treatment-eligibility, and unmet goals were substantially higher among non-Hispanic blacks. Moreover, disparities exist in treatment where Mexican-Americans and people of 'other races/ethnicities' were largely untreated despite having indication.
RESUMO
The 2017 American College of Cardiology/American Heart Association Guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults reduced the systolic/diastolic blood pressure thresholds to define hypertension, including recommendations about treatment initiations and goals. We estimated the age-stratified prevalence, treatment status, and factors associated with hypertension among US adults aged ≥ 20 years based on this guideline. This cross-sectional study used the 2011-2016 National Health and Nutrition Examination Survey data. The primary outcomes were the presence and treatment status of hypertension. Among 16,103 participants, the proportions (95% confidence interval) of hypertensive, treatment-indicated, untreated individuals among treatment-indicated, and treatment goals not met among treated for hypertension by age groups were, respectively, 17.4% (15.8-19.1), 6.9% (6.1-7.8), 67.6% (61.0-73.5), and 58.6% (46.1-70.2) among 20-34 years; 39.2% (37.0-41.5), 24.4% (22.4-26.5), 41.8% (37.7-46.0), and 50.4% (44.7-56.1) among 35-49 years; 62.3% (60.1-64.6), 51.4% (49.0-53.8), 31.0% (28.2-34.0), and 51.9% (47.6-56.1) among 50-64 years; 77.7% (75.3-79.8), 77.0% (74.7-79.2), 27.0% (24.3-29.8), and 63.1% (59.4-66.5) among ≥ 65 years; and 46.8% (45.4-48.3), 36.9% (35.4-38.5), 33.2% (30.9-35.5), and 56.7% (54.1-59.3) among overall population. Despite some dissimilarities, the prevalence, treatment eligibility, and odds of hypertension were higher among non-Hispanic blacks and among people with high cholesterol, low high-density lipoprotein, chronic kidney disease, diabetes, increased body weight, and low leisure-time physical activity in all age strata. The prevalence and treatment eligibility were high among adults from all age groups; however, a significant proportion of participants, especially those who were younger, had blood pressure levels above the treatment goals or were untreated. Addressing the associated characteristics from a younger age may help prevent the complications of hypertension.

INTRODUCTION: Although the prevalence of underweight is declining among Indian women, the prevalence of overweight/obesity is increasing. This study examined the prevalence and factors associated with underweight and overweight/obesity among reproductive-aged (i.e., 15-49 years) women in India. METHODS: This cross-sectional study analyzed data from the 2015-16 National Family Health Survey. The Asian and World Health Organization (WHO) recommended cutoffs for body mass index (BMI) were used to categorize body weight. The Asian and WHO BMI cutoffs for combined overweight/obesity were ≥ 23 and ≥ 25 kg/m2, respectively. Both recommendations had the same cutoff for underweight, < 18.5 kg/m2. After prevalence estimation, logistic regression was applied to investigate associated factors. RESULTS: Among 647,168 women, the median age and BMI was 30 years and 21.0 kg/m2, respectively. Based on the Asian cutoffs, the overall prevalence of underweight was 22.9%, overweight was 22.6%, and obesity was 10.7%, compared to 15.5% overweight and 5.1% obesity as per WHO cutoffs. The prevalence and odds of underweight were higher among young, nulliparous, contraceptive non-user, never-married, Hindu, backward castes, less educated, less wealthy, and rural women. According to both cutoffs, women who were older, ever-pregnant, ever-married, Muslims, castes other than backwards, highly educated, wealthy, and living in urban regions had higher prevalence and odds of overweight/obesity. CONCLUSION: The prevalence of both non-normal weight categories (i.e., underweight and overweight/obesity) was high. A large proportion of women are possibly at higher risks of cardiovascular and reproductive adverse events due to these double nutrition burdens. Implementing large-scale interventions based on these results is essential to address these issues.
RESUMO
OBJECTIVES: This study aimed to investigate the factors associated with low birth weight (LBW) in Afghanistan. DESIGN: Cross-sectional study. SETTING: This study used data collected from the Afghanistan Demographic and Health Survey 2015. PARTICIPANTS: Facility-based data from 2773 weighted live-born children enrolled by a two-stage sampling strategy were included in our analysis. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was LBW, defined as birth weight <2.5kg. RESULTS: Out of 2773 newborns, 15.5% (n=431) had LBW. Most of these newborns were females (58.3%, n=251), had a mother with no formal schooling (70.5%, n=304), lived in urban areas (63.4%, n=274) or lived in the Central region of Afghanistan (59.7%, n=257). In multivariable analysis, residence in Central (adjusted OR (AOR): 3.4; 95% CI 1.7 to 6.7), Central Western (AOR: 3.0; 95% CI 1.5 to 5.8) and Southern Western (AOR: 4.0; 95% CI 1.7 to 9.1) regions had positive association with LBW. On the other hand, male children (AOR: 0.5; 95% CI 0.4 to 0.8), newborns with primary maternal education (AOR: 0.5; 95% CI 0.3 to 0.8), birth interval ≥48 months (AOR: 0.4; 95% CI 0.1 to 0.8), belonging to the richest wealth quintile (AOR: 0.2; 95% CI 0.1 to 0.6) and rural residence (AOR: 0.3; 95% CI 0.2 to 0.6) had decreased odds of LBW. CONCLUSIONS: Multiple factors had association with LBW in Afghanistan. Maternal, Neonatal and Child Health programmes should focus on enhancing maternal education and promoting birth spacing to prevent LBW. To reduce the overall burden of LBW, women of the poorest wealth quintiles, and residents of Central, Central Western and South Western regions should also be prioritised. Further exploration is needed to understand why urban areas are associated with higher likelihood of LBW. In addition, research using nationally representative samples are required.

Globally, complications of raised blood pressure are fundamental public health issues. There has been limited research if prevalence and risk factors vary by sex in many countries, including Bangladesh. We stratified the prevalence and associated factors of prehypertension and hypertension according to sex in Bangladesh. This cross-sectional study analyzed the Bangladesh Demographic and Health Survey 2011 data. After estimating prevalence according to sex, multilevel logistic regression was applied to obtain associated factors. This study analyzed data of 3876 males and 3962 females aged ≥35 years. The prevalence of hypertension was 19.4% (95% confidence interval [CI]: 18.0-21.0) among males and 31.9% (95% CI: 30.1-33.6) among females. Among both males and females, prevalence and odds of hypertension increased with age, overweight/obesity, diabetes, upper wealth status, and residence in some divisions. Education level was a significant positive correlate of hypertension for males only. Males and females had similar prevalence of prehypertension, 27.2% (95% CI: 25.6-28.8) and 27.6% (95% CI: 26.0-29.2), respectively. Characteristics such as older age, overweight/obesity, and diabetes were associated with higher prevalence and odds of prehypertension among females; prehypertension among males was associated with advancing age, overweight/obesity, education level, wealth status, and division of residence. In Bangladesh, almost half of the males and females could have increased risks of complications resulting from hypertension and prehypertension. Addressing the characteristics associated with higher prevalence or odds of these conditions is crucial. Several common risk factors indicate that a common prevention and control strategy could work for both sexes.
