Background: Raised body mass index (obesity and overweight), is abnormal or excessive accumulation of fat that may impair health.The prevalence of obesity in Nigerian adolescents ranges between 1 and 10%.In children, raised body mass index is complicated with the development of cardiovascular diseases,which are consequences of arterial stiffness. The hallmark of arterial stiffness is wide pulse pressure which precedes isolated elevation of systolic blood pressure. Other manifestations of arterial stiffness are elevated diastolic blood pressure and increased mean arterial pressure. This study educated the students on healthy lifestyle and checked their cardiovascular indices.Methods: This was a descriptive cross-sectional study of students. Their weight, height and blood pressure were measured and cardiovascular indices were calculated.Results: There were 248 students, age between 8 and 16 years, 135 (54.4%) were males with adolescents comprising 96.8%. The prevalence rate of wide pulse pressure, raised body mass index, elevated blood pressure and increased mean arterial pressure was 26.6%, 16.1%, 8.5% and 4.0% respectively. More females and early adolescents comparably had raised body mass index.Conclusions: The mean values for cardiovascular indices were comparably higher in those with raised body mass index.

1. The aim of the present study was to evaluate whether metabolic factors are linked to the steady component and the pulsatile component of blood pressure, evaluated as mean arterial pressure and pulse pressure respectively, in a sex-specific manner. 2. A cohort of 299 subjects (152 males, 147 females; 25–80 years of age) was studied. Patients presenting congestive heart failure, coronary insufficiency, severe valvular heart disease, neurological accident in the last 6 months, renal or respiratory failure, cancer, diabetes mellitus or acute infectious disease were excluded. None of the women was taking oral contraceptives or oestrogen supplementation. All cardioactive drugs were withdrawn at least 2 weeks before the subjects entered the study. 3. Men presented higher mean arterial pressure (120 ± 15 compared with 115 ± 16 mmHg, P < 0.01) and lower pulse pressure values (63 ± 16 compared with 67 ± 18 mmHg, P < 0.05) than women. In men, no significant relation between mean arterial pressure and the tested variables was detected; multiple regression analysis demonstrated that age contributed independently to the model for pulse pressure with a multiple r2 of 0.10 (P < 0.01). In women, body mass index contributed independently to the model for mean arterial pressure, with a multiple of 0.12 (P < 0.005); age and, to a lesser extent, body mass index, glycaemia and triglyceridaemia persisted as independent determinants of pulse pressure at the multiple regression analysis, with a multiple r2 of 0.20 (P < 0.001). 4. Our findings suggest that metabolic risk factors are associated differently with pulse pressure and mean arterial pressure values in the two sexes.

Introduction: Modern lifestyle has resulted in an increased prevalence of cardiovascular and respiratory diseases along with being overweight. An interaction between the three factors has also been demonstrated. Aim: The study aimed to assess the relationship of Body Mass Index (BMI), Mean Arterial Pressure (MAP) and Peak Expiratory Flow Rate (PEFR) in healthy individuals. Materials and Methods: This cross-sectional, observational study was done in the Department of Physiology, KGMU, Lucknow from 30 July 2019 to 30 July 2020. Forty healthy individuals, aged 18-35 years were assessed for height, weight, blood pressure and spirometric parameter of PEFR. PEFR was chosen as it was a reliable representative of airways functioning. PEFR reflects proximal airway calibre changes which might be due to effect of airway geometry. A correlation test was run to test the relation between BMI and PEFR and MAP and PEFR. Results: A weak correlation (r=-0.136) was noted between BMI and PEFR indicating that as BMI increased, PEFR compromised. A linear correlation was observed between MAP and PEFR. Conclusion: The present study confirms a weak association of BMI and MAP with PEFR.

Introduction and Objective: The excess cardiovascular morbidity and mortality in hyperthyroidism and Graves’ disease (GD) is inadequately understood. We aimed to elucidate whether well-established cardiovascular risk factors such as arterial stiffness in terms of pulse wave velocity (PWV) and blood pressure differ in GD and controls. Methods: This was a cross-sectional study comparing 55 hyperthyroid patients with newly diagnosed GD and 55 euthyroid, population-based controls matched for age, sex and menopausal status. PWV and blood pressure were measured in office (SphygmoCor Xcel) and 24-h ambulatory settings (Arteriograph). Differences between groups were assessed using adjusted linear regression analysis. Results: Compared to controls, GD patients showed higher PWV in the 24-h but not in the office setting with an adjusted 24-h PWV difference of 1.0 (95% CI: 0.6–1.5) m/s. PWV was higher in GD at both day and night, and nightly PWV dipping was lower (–5.5, 95% CI: –10.4 to –0.6%). Furthermore, central and brachial pulse pressure was significantly higher in both the office and 24-h setting, whereas nightly central pulse pressure dipping was significantly lower in GD (–5.4, 95% CI: –10.5 to –0.2%). Mean arterial pressure did not differ between the groups. Conclusions: Despite comparable blood pressure, GD is associated with a higher 24-h PWV that was not detected in the office setting. Pulse pressure was higher in GD, whereas mean arterial pressure did not differ between the groups. Longitudinal studies should pursue whether higher PWV might be a piece to the puzzle of understanding the increased risk of cardiovascular disease in hyperthyroidism and GD.

Abstract: Adolescence is a vulnerable age group to nutrition imbalance disorders. One complication of high anthropometric level is increased blood pressure or hypertension. This study was aimed to determine the relationship between body mass index and waist size to blood pressure among senior high school students in Tomohon. This was an analytical observational study with a cross sectional design. Subjects were 307 students of SMA Kristen 2 Binsus Tomohon consisting of 139 males and 168 females. Measurement of weight, height, and waist circumference (WC) as well as calculation of body mass index (BMI) were performed on all subjects. The Kolmogorof-Smirnov test showed that the data were not distributed normally. The Spearman correlation test obtained a p-value of 0.000 (p<0.05) for the correlation between BMI and WC to blood pressure (systolic and diastolic blood pressures). In conclusion, there were significant relationships between BMI and blood pressure as well as between waist circumference and blood pressure.Keywords: body mass index, waist size, blood pressure Abstrak: Usia remaja sangat rentan terhadap gangguan keseimbangan gizi.

Abstract Background Elderly patients have a relatively high cardiovascular risk due to increased arterial stiffness, elevated blood pressure and decreased amounts of elastin in the arteries. The composition of the media layer in the arterial wall, comprising elastin, collagen, smooth muscle cells, proteoglycans, fibronectin and fibrillin-1, influences its mechanical properties. Mutations in the fibrillin-1 gene leads to increased aortic stiffness, elevated pulse pressure and aortic root dilatation. This study investigates whether there is a sex difference among hypertensive elderly patients regarding blood pressure, arterial stiffness and fibrillin-1 genotypes. Methods A total of 315 hypertensive subjects (systolic blood pressure > 140 mmHg) were included in this study (155 men and 160 women aged 71–88 years). Aortic pulse wave velocity and augmentation index were determined using SphygmoCor, and brachial blood pressure was measured using an oscillometric technique. Fibrillin-1 was genotyped by polymerase chain reaction and with a capillary electrophoresis system. Results Females showed a significantly higher peripheral mean arterial pressure (females; 107.20 mmHg, males 101.6 mmHg, p = 0.008), central mean arterial pressure (females; 107.2 mmHg, males 101.6 mmHg p = 0.008), central systolic blood pressure (females; 148.1 mmHg, males 139.2 mmHg, p <  0.001) and central pulse pressure (females; 68.9 mmHg, males 61.6 mmHg, p = 0.035) than males. Females with the Fibrillin-1 2/3 genotype showed a significantly higher augmentation index (FBN1 2/3; 39.9%, FBN1 2/2 35.0%, FBN1 2/4 35.8, p = 0.029) and systolic blood pressure (FBN1 2/3; 174.6 mmHg, FBN1 2/2168.9 mmHg, FBN1 2/4169.9 mmHg, p = 0.025) than females with the 2/2 and 2/4 genotypes. Conclusion The findings of this study may indicate that hypertensive elderly females, especially elderly females with Fibrillin-1 2/3, have increased systolic blood pressure and arterial stiffness.

Hipertensiadalah penyebab kematian utama di Indonesia. Kematian akibat hipertensi lebih banyak terjadi di perkotaan dibandingkan di desa. Tingginya kejadian hipertensi dipengaruhi oleh faktor yang dapat dikontrol (obesitas,berat badan lebih, konsumsi garam berlebih,aktivitas fisik rendah, perokok, dan konsumsi alkohol) dan faktor yang tidak dapat dikontrol (genetik, usia, dan jenis kelamin). Penelitian bertujuan memberikan gambarandistribusi tekanan darah dan indeks massa tubuh (IMT) pendudukperempuan di kota maupun di desa.Desain penelitian adalah deskriptif kuatitatif dengan pendekatan cross sectional. Data primer didapatkan melalui pengukuran tekanan darah, tinggi badan dan berat badan. Penelitian dilakukan di Desa Kutowinangun Kidul, Kecamatan Tingkir,Salatiga yang mewakili penduduk perempuan di perkotaan dan Desa Batur, Kecamatan Getasan, Kabupaten Semarangyang mewakili penduduk perempuan pedesaan. Adapun jumlah sampel masing-masing 66 respondendan 72responden. Hasil penelitian menunjukkan bahwa kejadian penyakit hipertensi, resiko obese dan obese lebih didominasi oleh respondendi perkotaan dibandingkan di pedesaan dengan rentang usia di atas 46 tahun. Respondendi desa dengan indeks massa tubuh normal cenderung mengalami pre-hipertensi (8,3%) dan hipertensi stadium I (6,9%) sementararesponden dengan resiko obese dan obese cenderung mengalami hipertensi stadium I (1,4%).Respondendi kota dengan indeks massa tubuh normal cenderung mengalami pre hipertensi (6,06%), hipertensi stadium I (4,5%) dan II (7,5%). Responden dengan resiko obese cenderung mengalami hipertensi stadium I (4,5%), dan responden dengan obese I dan II cenderung mengalami pre-hipertensi (4,5%).   Hypertension is the leading cause of death in Indonesia. Deaths due to hypertension are more common in urban areas than in villages. The high incidence of hypertension is influenced by factors that can be controlled (obesity, overweight, excessive salt consumption, low physical activity, smokers, and alcohol consumption) and factors that cannot be controlled (genetic, age, and sex). The study aimed to provide an overview of blood pressure distribution and body mass index (BMI) of female residents in cities and villages. The study design was descriptive quantitative with a cross sectional approach. Primary data was obtained through measurements of blood pressure, height and weight. The study was conducted in Kutowinangun Kidul Village, Tingkir Subdistrict, Salatiga representing women in urban areas and Batur Village, Getasan Subdistrict, Semarang Regency, representing rural women. The number of samples was 66 respondents and 72 respondents respectively. The results showed that the incidence of hypertension, the risk of obese and obese was more dominated by respondents in urban areas than in rural areas with ages above 46 years. Respondents in villages with normal body mass index tended to experience pre-hypertension (8.3%) and stage I hypertension (6.9%) while respondents with obese and obese risk tended to experience stage I hypertension (1.4%). Respondents in cities with normal body mass index tended to experience pre-hypertension (6.06%), stage I hypertension (4.5%) and II (7.5%). Respondents with obese risk tended to experience stage I hypertension (4.5%), and respondents with obese I and II tended to experience pre-hypertension (4.5%).

Aim. To study the relationship between body mass index (BMI) and blood pressure (BP) on visual acuity among apparently healthy residents of Ekpoma, Esan West Local Government Area of Edo State, Nigeria. Methodology. This is a cross-sectional descriptive study among 225 subjects (ages of 18–35 years) from whom BP, body weight, and height were collected. Visual acuity was measured using the Snellen chart following standard procedures of number of letters seen at 6-metre distance. The data were then analyzed using SPSS version 17. Results. The sampled population consists of 112 male and 113 female (mean age 31.72±14.2 years). Majority (180) of the respondents had normal visual acuity. However, compared with the respondents with normal BMI (R19.61±1.5; L19.67±1.70), visual acuity of underweight (R18.53±2.30; L18.53±2.70) and obese (R15.68±4.79; L17.73±1.70) were more deviated. Similarly, compared with respondent with normal BP (120–125/80–85 mmHg; R18.00±2.53; L18.07±3.11), hypotensive (R15.5±7.35; L15.00±10.20), and hypertensive (R15.01±21.25; L15.00±11.91) respondents had deviated visual acuity. Conclusion. Abnormal body weight (underweight and obese) and BP (hypotension and hypertension) have potential negative impacts on visual acuity. Based on the observed relationship between weights, BP, and visual acuity, eye examinations can be included as regular screening exercise for abnormal BMI and BP conditions.

Background Evidence suggests that obesity may be related toearly onset of puberty in girls. However, few studies have found alink between body mass index (BMI) and puberty onset in boys.More study is needed to assess the relationship of BMI to penilelength and testicular volume.Objective To investigate the relationship ofBMI to penile lengthand testicular volume in adolescent boys.Methods A cross􀀿sectional study was carried out on adolescentboys aged 9 to 14 years in Secanggang District, Langkat Regency,North Sumatera Province in August 2009. Subjects' BMIs werecalculated by dividing body weight (BW) in kilograms by bodyheight (BH) in meters squared. Penile length (em) was measuredwith a spatula. We took the average of three measurements fromthe symphysis pubis to the tip of the glans penis. Testicular volume(mL) was estimated by palpation using an orchidometer. Pearson'scorrelation test (r) was used to assess the relationship of BMI topenile length and BMI to testicular volume.Resu lts There were 108 participants, consisting of 64primary school students and 44 junior high school students.Subjects' mean age was 11.7 (SO 1.62) years; mean BWwas 35.2 (SO 8.48) kg; mean BH was 1.4 (SO 0.11) m;mean BMI was 17.5 (SO 2.34) kg/m'; mean penile lengthwas 4.5 (SO 1.25) cm; and mean testicular volume was 3.6(SD 1.20) mL. We found no significant association betweenBMI and penile length (r􀀻-0.25, P􀀻0.06), nor betweenBMI and testicular volume (r􀀻-O.21; P􀀻O.09).Conclusion T here was no significant relationship ofBMI to penilelength nor BMI to testicular volume in adolescent boys.[Paediatr lndanes. 2012;52:267-71].

Background Whether or not norepinephrine infusions for support of hemodynamic status in patients with septic shock should be weight based is unknown. This situation is particularly pertinent in patients who are extremely overweight or obese. Objective To compare dosing requirements and effect of norepinephrine on blood pressure in obese and nonobese patients with septic shock. Methods In a retrospective cohort study, data on adult patients with septic shock who received norepinephrine infusion for support of hemodynamic status in a tertiary care, academic medical center were analyzed. Patients were categorized as obese (body mass index ≥ 30) or nonobese (body mass index &lt; 30). The primary outcome was dosing requirements of norepinephrine at 60 minutes after the start of the infusion. The secondary outcome was the log-transformed ratio of mean arterial pressure to norepinephrine. Results The final cohort consisted of 100 obese and 100 nonobese patients. Mean norepinephrine infusion rate at 60 minutes was 0.09 (SD, 0.08) μg/kg per minute in the obese group and 0.13 (SD, 0.14) μg/kg per minute in the nonobese group (P = .006). The non–weight-based dose at 60 minutes was 9 μg/min in obese patients and 8 μg/min in nonobese patients (P = .72). The log transformed mean arterial pressure to norepinephrine ratio at 60 minutes was 2.5 (SD, 0.9) in obese patients and 2.5 (SD, 0.8) in nonobese patients (P = .54) Conclusions Compared with nonobese patients, obese patients with septic shock require lower weight-based doses of norepinephrine and similar total norepinephrine doses.

Abstract Background: The use of contraceptives has become prevalent among women in Ethiopia. Oral contraceptive use has been suggested to trigger changes in glucose metabolism, energy expenditure, blood pressure, and body weight, among the various populations and ethnic groups. Objective: To elucidate the pattern of fasting blood sugar (FBS), blood pressure and body mass index (BMI) among combined oral contraceptive (COC) pills users, taking into account other confounding factors including socioeconomic conditions and physical activity status. Methods: An institution based cross-sectional study design was employed. A total of 110 healthy women using pills were recruited as cases. Another 110 healthy women not using any hormonal contraceptives were recruited as matched controls. A study was conducted between October 2018 and January 2019. Fasting Capillary blood sample was collected from the study participants for the estimation of the FBS level. Systolic and diastolic blood pressures were measured and means arterial blood pressure was calculated for each participant. Body weight and height were measured to compute body mass index. Data obtained was entered and analyzed using IBM SPSS version 23 software packages. Results: FBS level in users was significantly increased compared to controls (88.55 ± 7.89 vs. 86.00 ± 9.85 in users and controls respectively, P = 0.025). There was a significant difference in mean arterial blood pressure of users compared to controls (88.2 ± 8.48 vs. 86.0 ± 6.74 respectively, P=0.04). The mean weight and body mass index of users were significantly increased (P = 0.03 and P = 0.003, respectively). Changes in mean fasting blood sugar level and mean weight of users were independent (P = 0.27 and P = 0.46) to the duration of use (3-12, 13-24 and ≥ 25 months). On the other hand, changes in mean body mass index and mean arterial blood pressure of users were dependent of the duration of use (P = 0.03 and P = 0.000 respectively). Conclusions: Overall, oral contraceptive pills use appears to cause a 2.9% increase in fasting blood glucose level, a 2.5% increase in mean arterial blood pressure and a 3.9% increase in body mass index among the users.
