Obesity is a health disorder characterized by an increase in body weight, measured by waist circumference. High waist circumference is linked to potential development of non-communicable diseases. A systematic review study was used to explore health risks of high waist circumference through Google Scholar, Science Direct, Pubmed, and Proquest. Findings show that high waist circumference increased the risks of developing hypertension, type 2 diabetes mellitus, hypercholesterolemia, joint pain, low back pain, and hyperuricemia. It is recommended that government increase their role in raising public awareness to maintain healthy lifestyle.

Adult gains in body weight, excess adiposity, and intra-abdominal fat have each been associated with risk for type 2 diabetes mellitus (T2DM), forming the basis for preventive medicine guidelines and actuarial predictions using practical indices of weight (e.g., body mass index [BMI]) and waist circumference (WC). As obesity-related disease spreads beyond affluent western countries, application of WC thresholds to other populations has highlighted issues of their generalizability. For example, U.S. national health goals based on BMI < 25 kg/m2 and WC < 89 cm (women) and <102 cm (men) differ considerably with a recent law in Japan mandating intervention for older adults with WC exceeding 90 cm (women) and 85 cm (men). The U.S. military has also faced issues of generalizability of WC-based adiposity standards that are fair and achievable. Data from many studies indicate that WC is a reliable biomarker for T2DM risk, suggesting that, for adult men and women, action thresholds should be more stringent than current U.S. guidelines, and it would not be harmful to set worldwide targets somewhere below 90 cm for men and women, regardless of weight status. Medical technology has provided many great insights into disease, including modern imaging technologies that have differentiated fat depots that have the greatest influence on T2DM, but ultimately, an inexpensive measuring tape provides the most useful and cost-effective preventive measure for T2DM today. At some point in the future, a Star Trek-like abdominal body fat "tricorder" noninvasive assessment of tissue composition may provide an advantage over abdominal girth.

Background: The Body Mass Index, Waist Circumference and Waist by Hip ratio have linear relation with increase in blood pressure. This study will correlate blood pressure with these anthropometric measures in normal subjects to find out the subtle increase in which of these measure would linearly increase blood pressure. The aim is to find the better anthropometric measure to relate with blood pressure changes.Methods: One hundred and seventy five healthy medical students were enrolled for the study in Manipal College of Medical Sciences, Pokhara after getting ethical clearance. The mean reading of right brachial arterial blood pressure with mercury manometer in sitting position was taken. For anthropometric measures, body weight was measured in weighing scale and height and circumferences of waist and hip were taken with non elastic measuring tape. The data were used to derive required variables. Results: Out of 175 participants, 59% were male and remaining female. The non obese participants were 46.3% followed by obese (22.9%) as per Asia Pacific Guidelines for The Body Mass Index. The positive correlation of increase in Systolic and Diastolic components of blood pressure was statistically highly significant [P=0.00] in female with normal Waist Circumference and Waist by Hip ratio. However in general, SBP was positively correlated with Waist by Hip ratio [r=0.44] and DBP was positively correlated with Waist Circumference [r=0.43] and were statistically highly significant [P=0.00].Conclusions: The Waist Circumference and Waist by Hip Ratio have stronger correlation with blood pressure components than Body Mass Index even in normal subjects.Keywords: Blood pressure; body mass index; hip ratio; waist: waist circumference.

Background: Andropause occurs with slow development and is a physiological process in males. Andropause symptoms arise vary in individuals. One of the factors that influence these symptoms is obesity, especially central obesity with a waist circumference of >90 cm. Objective: The purpose of this study is to show the relationship between waist circumference and the event of andropause. Methods: This research is an analytical study with a cross-sectional study approach conducted in one of the government institutions of Badung Regency, Bali Province. The sampling technique used was purposive sampling. The subjects consisted of 40 male employees at aged around 35-60 years. The research data were obtained from filling out the Androgen Deficiency in Aging Male (ADAM) score questionnaire and direct measurement of waist circumference. The statistical analysis used was the Chi-Square test. Results: The results showed that from 40 subjects, 23 (57.5%) subjects had a waist circumference of >90 cm, and a normal waist circumference of <90 cm in 17 (42.5%) subjects. There were 22 subjects (55.0%) who experienced andropause and 18 (45.0%) subjects who did not experience andropause. It was found that there was a significant relationship between waist circumference and the event of andropause among male employees in government institutions of Badung Regency (p = 0.001, OR = 11.7). Conclusion: The study has found that higher in waist circumference may contribute in the event of andropause. For further studies should takes a higher number of subjects to make it more accurate in wider population.

Purpose. Little is known about obesity-related health issues among American Indian and Alaska Native (AIAN) populations. Approach. A large cohort of AIAN people was assembled to evaluate factors associated with health. Setting. The study was conducted in Alaska and on the Navajo Nation. Participants. A total of 11,293 AIAN people were included. Methods. We present data for body mass index (BMI, kg/m2) and waist circumference (cm) to evaluate obesity-related health factors. Results. Overall, 32.4% of the population were overweight (BMI 25-29.9 kg/m2), 47.1% were obese (BMI ≥ 30 kg/m2), and 21.4% were very obese (BMI, ≥ 35 kg/m2). A waist circumference greater than 102 cm for men and greater than 88 cm for women was observed for 41.7% of men and 78.3% of women. Obese people were more likely to perceive their health as fair/poor than nonobese participants (prevalence ratio [PR], 1.91; 95% CI, 1.71-2.14). Participants younger than 30 years were three times more likely to perceive their health as being fair or poor when their BMI results were 35 or greater compared with those whose BMI results were less than 25 kg/m2. A larger BMI was associated with having multiple medical conditions, fewer hours of vigorous activity, and more hours of television watching. Conclusions. Given the high rates of obesity in AIAN populations and the association of obesity with other health conditions, it is important to reduce obesity among AIAN people.

Background: African American children and adolescents make up a disproportion­ately large segment of those classified as overweight and obese. The purpose of this study was to examine social and behavioral factors associated with accelerated ac­cumulation of weight and adiposity among this group.Methods: The data for this cross-sectional study were drawn from the Jackson Heart KIDS Pilot Study – an offspring cohort study comprising 12- to 19-year-old descen­dants of Jackson Heart Study participants (N=212). Body mass index (BMI) and waist circumference were the outcomes of interest. Daily hassles, fruit and vegetable consumption, physical activity, television watching, parent/grandparent weight status and participant birth weight, age and sex were the independent variables included in the analyses.Results: Males and females were equally represented in the study and the mean BMI and waist circumference for adolescents in the study was 25.81±7.78 kg/m2 and 83.91 ± 19.81 cm, respectively. Fully adjusted linear regression models for the total sample produced results indicating that age, televi­sion viewing, weight control, and parental weight status were positively associated with BMI and waist circumference, respectively. Findings from sex-stratified models for BMI and waist circumference indicated that the significance of coefficients for age, television viewing, and parent/grandparent weight status varied by sex.Conclusions: Knowledge is limited about how sex or gender interact with social and behavioral factors to influence African Americans' health and additional studies are needed to specify how these factors interact to accelerate weight gain and adipose tissue accumulation over the life course.Ethn Dis. 2021;31(3):453-460; doi:10.18865/ed.31.3.453

Therefore, we aimed to analyse the associations between the frequency of drinking water consumption and body weight and waist circumference changes in an elderly Mediterranean cohort. Methods: A total of 1832 elderly participants (aged 55e75 years) with metabolic syndrome from the PREDIMED-Plus study with baseline data on drinking water and other beverages assessed by a validated 32-item Spanish fluid-intake questionnaire and with data on body weight (BW) and waist circumference (WC) at 1-year and 2-year were included in these prospective analyses. Multivariable linear regression models were fitted to assess the b-coefficients and 95% confidence interval (CI) for BWand WC changes in terms of categories of baseline drinking water consumption (tap water and bottled water). The theoretical effect on BWand WC of replacing several beverages with drinking water was assessed using mathematical models. Results: The baseline frequency of drinking water consumptionwas inversely associated with 1-year and 2- year changes in BW. b-coefficients (95%CI) across categories ofwater consumption (<2.5, 2.5 to <5, 5 to < 7.5, 7.5 servings/d) expressed in % of weight changes at 2 years of follow-up were 0.0, 0.80 ( 1.48, 0.12), 1.36 ( 2.18, 0.54), and 1.97 ( 3.09, 0.86), respectively. Individuals in the two highest categories of drinkingwater consumption (5 to < 7, and 7.5 servings/d) also showed a higher decrease inWC (expressed as % of change) after 2 years of follow-up: 1.11 ( 1.96, 0.25) and 1.45 ( 2.66, 0.24) compared to the reference intake (<2.5 servings/day), after adjustment for potential confounding factors. The theoretical replacement of soups, beers, spirits, hot beverages, dairy beverages, and other beverages group with drinking water was associated with greater reductions in BWat one- and two-years of follow-up. Conclusions: Drinking water consumption was inversely associated with 2-year adiposity changes in an elderly Mediterranean cohort at high cardiovascular risk. Our results also suggest that the consumption of drinking water instead of energy-containing beverages is associated with lower weight gain. ; Spanish Government European Commission ; European Union ERDF/ESF, "A way to make Europe"/"Investing in your future" PI13/00272 PI13/01123 PI13/00462 PI13/00233 PI13/00728 PI14/01722 PI14/00636 PI14/01206 PI14/01919 PI14/01374 PI16/01873 PI16/01094 PI16/00501 PI16/00533 PI16/00366 ; Special Action Project entitled: Implementacion y evaluacion de una intervencion intensiva sobre la actividad fisica Cohorte PREDIMED-Plus grant ; European Research Council (ERC) ; European Commission 340918 ; Recercaixa Grant 2013ACUP00194 ; Generalitat Valenciana European Commission PROMETEO/2017/017 ; SEMER-GEN grant European Commission CB06/03 ; Department of Health of the Generalitat de Catalunya SLT006/17/00246 ; Ministerio de Ciencia, Innovacion y Universidades (MICINN) FPU 17/01925 ; ICREA under the ICREA Academia programme ; Spanish Ministry of Education, Culture and Sports FPU 17/01925 ; Juan de la Cierva-Formacion FJC2018-036016-I ; Ministry of Science, Innovation and Universities FPU 18/01703 ; Fernando Tarongi Bauza PhD Grant ; The European Union ERDF/ESF, "A way to make Europe"/"Investing in your future" PI17/00764 PI17/01827 PI17/01441 PI17/01732 PI17/00926 PI19/00309 PI19/01032 PI19/00576 PI19/00017 PI19/00781
