Self Reports

Psychological and physiological stress indices were taken from collegiate swimmers of both sexes prior to a practice session and prior to a meet. At another time these same individuals were administered a scale to ascertain their relative self-reported masculinity and femininity. Analysis of covariance demonstrated that 14 males had higher systolic blood pressure than 13 females but lower self-reported feelings of anxiety and hostility associated with the stress of competition. Sex differences in relative masculinity and femininity provided the key to interpretation.

Postmenopausal women have a higher prevalence of hypertension compared to premenopausal women. Hypertension is a risk factor for cardiovascular diseases, the prevalence of which is ever increasing. This study investigated the effects of long-term acupuncture on lowering the blood pressure of postmenopausal women with prehypertension and stage 1 hypertension. Participants were 122 postmenopausal women aged less than 65 years, diagnosed with prehypertension or stage 1 hypertension (systolic blood pressure 120–159 mmHg or diastolic blood pressure 80–99 mmHg). We used a propensity score-matched design. The experimental group (n = 61) received acupuncture for four weeks every six months over a period of two years. The control group (n = 61) received no intervention. An Analysis of covariance (ANCOVA) was performed for the primary efficacy analysis. Relative risk ratios were used to compare group differences in treatment effects. Acupuncture significantly reduced the participants’ diastolic blood pressure (−9.92 mmHg; p < 0.001) and systolic blood pressure (−10.34 mmHg; p < 0.001) from baseline to follow-up. The results indicate that acupuncture alleviates hypertension in postmenopausal women, reducing their risk of developing cardiovascular diseases and improving their health and quality of life.

AbstractObjectivesTo investigate sex differences in risk factors for incident myocardial infarction (MI) and whether they vary with age.DesignProspective population based study.SettingUK Biobank.Participants471 998 participants (56% women; mean age 56.2) with no history of cardiovascular disease.Main outcome measureIncident (fatal and non-fatal) MI.Results5081 participants (1463 (28.8%) of whom were women) had MI over seven years’ mean follow-up, resulting in an incidence per 10 000 person years of 7.76 (95% confidence interval 7.37 to 8.16) for women and 24.35 (23.57 to 25.16) for men. Higher blood pressure indices, smoking intensity, body mass index, and the presence of diabetes were associated with an increased risk of MI in men and women, but associations were attenuated with age. In women, systolic blood pressure and hypertension, smoking status and intensity, and diabetes were associated with higher hazard ratios for MI compared with men: ratio of hazard ratios 1.09 (95% confidence interval 1.02 to 1.16) for systolic blood pressure, 1.55 (1.32 to 1.83) for current smoking, 2.91 (1.56 to 5.45) for type 1 diabetes, and 1.47 (1.16 to 1.87) for type 2 diabetes. There was no evidence that any of these ratios of hazard ratios decreased with age (P>0.2). With the exception of type 1 diabetes, the incidence of MI was higher in men than in women for all risk factors.ConclusionsAlthough the incidence of MI was higher in men than in women, several risk factors were more strongly associated with MI in women compared with men. Sex specific associations between risk factors and MI declined with age, but, where it occurred, the higher relative risk in women remained. As the population ages and the prevalence of lifestyle associated risk factors increase, the incidence of MI in women will likely become more similar to that in men.

Background: ‪The aim of this work was to examine the extent to which cardiorespiratory fitness, blood pressure, and optimism/pessimism predict adults’ satisfaction with life. Material and methods: ‪Sixty-eight adults seeking cardiovascular health screening in a private clinic were tested. Participants’ blood pressure, optimism/pessimism, and satisfaction with life were recorded. The YMCA cycle ergometer test was used for estimating participants’ aerobic fitness (VO2 max). Based on 140/90 mm Hg blood pressure cut-off value, participants were classified into two groups. Results: ‪A bootstrapped hierarchical multivariate regression analysis revealed that VO2 max, systolic blood pressure, optimism, and pessimism jointly accounted for 46% of the variance (R2 = 0.501, R2 adjusted = 0.462) in life satisfaction. Furthermore, a bootstrapped multivariate analysis of covariance indicated that Stage 2 hypertensives reported lower life satisfaction (p = 0.007) than the others with lower blood pressure readings. Conclusions: ‪This study is the first to reveal that almost half of the total variance in life satisfaction is accounted by cardiorespiratory fitness, systolic blood pressure, optimism, and pessimism. The present work also shows that individuals in Stage 2 hypertension are less satisfied with their lives than individuals with lower blood pressure values. These preliminary findings should stimulate both epidemiological and longitudinal research in the area.

Excessive dietary fat intake is related to metabolic dysfunction and enhances susceptibility to hypertension and cognitive impairment. Although there are sex differences in the prevalence and progression of these diseases, few studies have investigated sex differences in cardio-metabolic and cognitive parameters in rats with high-fat diet-induced metabolic dysfunction. To better reflect actual clinical conditions, sex-differences in rats with high-fat diet-induced metabolic dysfunction were evaluated. Male and female Sprague-Dawley rats were fed a high-fat diet to induce metabolic dysfunction and intraperitoneally injected with N-nitro-L-arginine methyl ester and scopolamine to model vulnerability to hypertension and cognitive impairment, respectively, whereas control rats were fed a regular diet and treated with distilled water and 0.9% saline. Male experimental rats showed significantly higher systolic blood pressure than female experimental animals. More importantly, acetylcholine-induced relaxation of carotid arteries was decreased only in the male experimental rats, revealing a significant difference compared with female experimental rats. These findings provide evidence for individualized sex-based management of patients with metabolic dysfunction and susceptibilities to hypertension and cognitive impairment. Impact statement Excessive dietary fat intake plays important roles in the process of metabolic dysfunction and increases susceptibilities to chronic diseases such as hypertension. Few previous studies, however, have accurately reflected real-world medical conditions. In addition, studies performed to date have not examined detailed sex-differences in cardio-metabolic and cognitive parameters, precluding the development of sex-tailored interventions for patients with metabolic dysfunction who are susceptible to hypertension and cognitive impairment. In this study, using rats with HFD-induced metabolic dysfunction that made them susceptible to hypertension and cognitive impairment, we demonstrate that male rats show greater impairment of acetylcholine-induced vasorelaxation of the carotid artery and systolic blood pressure compared to female rats. These findings may provide a basis for the early detection of carotid artery dysfunction and systolic blood pressure increase, especially in males.

Regular exercise is recommended for adults experiencing hypertension with low and moderate cardiovascular risk. High intensity interval training (HIIT) is an efficient training method and has a better cardiometabolic protective effect. The purpose of this study was to determine sex differences in blood pressure and body composition after high intensity interval training. Twenty two adults with hypertension and central obesity (male n = 16, age 35.56 ± 4.56 years, waist circumference 98.85 ± 6.85 cm, systolic blood pressure 134.22 ± 2.86 mmHg, diastolic blood pressure 85.03 ± 6.58 mmHg) - (female n = 6, age 37.83 ± 5.46 years, waist circumference 95.09 ± 7.49 cm, systolic blood pressure 133.50 ± 6.47 mmHg, diastolic blood pressure 89.80 ± 5.94 mmHg) participated in a high intensity interval training (HIIT). The HIIT consisted of 3x4 minutes training at 77– 95% of maximum heart rate interspersed by 3 minutes of active rest at 64-76% of of maximum heart rate. The training was conducted three sessions per week for 10 weeks. Systolic blood pressure and diastolic blood pressure were significantly reduced in men. There was an improvement in body composition parameters, including a decrease in waist-to-hip ratio, visceral fat, and body fat mass in men (p 0.05). Waist circumference decreased in both men and women (p 0.05). It concludes that there are sex differences in cardiometabolic adaptation after HIIT.

IntroductionTo examine the association of sleep duration, insomnia, and obstructive sleep apnea (OSA) with hemoglobin A1c (HbA1c) in a cohort of patients with type 2 diabetes (T2D) on glucose-lowering medications.Research design and methods13 346 patients with T2D were included in the present analysis (mean age: 60.2 years; 56.6% were on antidiabetic drug monotherapy; 43.4% received at least two glucose-lowering medications). Sleep duration (short: ≤6 hours/day; normal: 7–8 hours/day; long: ≥9 hours/day) and frequency of insomnia symptoms were self-reported. The risk of OSA was considered high if at least two of the following conditions were fulfilled: regular snoring, frequent daytime sleepiness, and either obesity (≥30 kg/m2) or hypertension (systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg). Associations between sleep variables and HbA1c were investigated by analysis of covariance or linear regression (adjusted for, eg, participants’ age, sex, ethnic background, and systolic blood pressure).ResultsLong sleep duration and a high risk for OSA were independently associated with higher HbA1c values (long vs normal sleep duration: +0.10% (95% CI 0.03 to 0.18); high vs low risk for OSA: +0.07% (95% CI 0.02 to 0.11), both p=0.004). No robust association was found of short sleep duration and frequent insomnia symptoms with HbA1c. Finally, a positive dose–response association between the number of sleep problems per subject (range: 0–3) and HbA1c was observed (β=0.04% (0.02 to 0.06), p=0.002). However, all significant associations were small.ConclusionScreening for and treatment of sleep problems may help lower HbA1c levels in patients with T2D on glucose-lowering medications.

Background: Whether there are sex differences in hemodynamic profiles among people with elevated blood pressure is not well understood and could guide personalization of treatment. Methods and results: We described the clinical and hemodynamic characteristics of adults with elevated blood pressure in China using impedance cardiography. We included 45,082 individuals with elevated blood pressure (defined as systolic blood pressure of ≥130 mmHg or a diastolic blood pressure of ≥80 mmHg), of which 35.2% were women. Overall, women had a higher mean systolic blood pressure than men (139.0 [±15.7] mmHg vs 136.8 [±13.8] mmHg, P<0.001), but a lower mean diastolic blood pressure (82.6 [±9.0] mmHg vs 85.6 [±8.9] mmHg, P<0.001). After adjusting for age, region, and body mass index, women <50 years old had lower systemic vascular resistance index (beta-coefficient [β] -31.68; 95% CI: -51.18, -12.19) and higher cardiac index (β 0.07; 95% CI: 0.04, 0.09) than men of their same age group, whereas among those ≥50 years old women had higher systemic vascular resistance index (β 120.43; 95% CI: 102.36, 138.51) but lower cardiac index (β -0.15; 95% CI: -0.16, -0.13). Results were consistent with a propensity score matching sensitivity analysis, although the magnitude of the SVRI difference was lower and non-significant. However, there was substantial overlap between women and men in the distribution plots of these variables, with overlapping areas ranging from 78% to 88%. Conclusions: Our findings indicate that there are sex differences in hypertension phenotype, but that sex alone is insufficient to infer an individual's profile.
