Sex differences in the awareness, treatment, and control of hypertension in China: a systematic review with meta-analyses

Hypertension is the major cause of preventable disease burden in China. However, limited evidence is available on sex differences in the awareness, treatment, and control of hypertension. We assessed sex differences in the awareness, treatment, and control of hypertension in China. A systematic search of four English language and four Chinese-language databases was conducted to identify studies conducted from 2005 that reported sex-specific data on the awareness, treatment, and control of hypertension in China. Random effects meta-analysis weighted by the inverse of the variances were used to obtain pooled sex-specific rates and women-minus-men differences, and their 95% confidence intervals (CI). Overall, 57 studies comprising 2,155,829 individuals (55% women) were included. Awareness (53% in women vs. 47% in men), treatment among all (44% vs. 38%), treatment among aware (65% vs. 60%), control among all (17% vs. 14%), and control among treated (27% vs. 27%) were low for both sexes, but more favourable in women than men. The corresponding women-minus men difference was 7% (95% CI: 6; 8%) for awareness, 6% (5; 8%) for treatment among all, 6% (2; 9%) for treatment among aware, 3% (2; 3%) for control among all, and 0% (-2; 1%) for control among treated. Awareness, treatment, and control of hypertension in China is low in both sexes, but greater in women than men. Sex-specific interventions may be needed to efficiently combat the burden of hypertension.The Japanese Society of Hypertension Hypertension Research With nearly 20% of the world's population, China represents a large proportion of the global burden of hypertension; 17% of women and 22% of men in China had hypertension in 2015. 1,3 The management of hypertension in China is poor; 4,5 a recent report from a nationally representative survey indicated that approximately 60% of hypertensive individuals in China are not aware of their condition, about two-thirds are not treated, and less than 10% have proper control. 6 Several studies, from mostly Western populations, have reported that women have greater awareness of their hypertension and higher rates of treatment and control than men. [7][8][9][10][11][12][13] Sex differences in the awareness, treatment, and control of the condition have not been assessed in detail in China. However, these may differ from those in the West because of major cultural and sociodemographic differences, as well as differences in health care delivery and utilization. Accurate information about sex differences in the awareness, treatment, and control of the condition is important, not only to provide a baseline picture from which progress can be monitored, but also to inform the development of better approaches to improve the control of hypertension in both women and men in China.The aim of this study was to conduct a systematic review with meta-analyses to provide most comprehensive contemporary estimates of sex differences in the awareness, treatment, and control of hypertension in China.

Comments on momentum aperture of 100 GeV/n Au runs in RHIC

Zhang¹

2011

In RHIC 2010 100 GeV/n Au run, the momentum aperture has been an issue in the re-bucketing and the beam intensity lifetime in store. Both Blue and Yellow beams with comparable storage RF voltage and peak current have suffered more beam loss than in Run 2007 [1]. In this note, some comments are made for the momentum aperture of the lattices used from the Au runs in 2007, 2008 and 2010. From the wigglings and the beam decays of each lattice, information regarding the machine momentum aperture is presented. Several directions in further improvement are discussed. 2 Wigglings Since chromaticity measurement with wigglings is a necessary step before a new lattice put into operation, it is possible to compare the momentum aperture in recent Au runs. With a radial shift of around 1 mm in the wigglings, a momentum deviation of around 0.001 can be used for a chromaticity measurement and corrections at store. Usual lattice commissioning makes this measurement not too difficult, which is often accompanied with small beam losses, such as that in Au run 2007 with Au72. In case that a large beam loss occurs, one needs to further correct the orbit, the tune, and the non-linearities as well. The effort could be significant if the results were less than satisfactory, such as the case in Au run 2010, with Au102 and Au104. It is always possible that optimum machine tuning was missed out, and therefore the machine could have been better tuned. However, with the best wigglings performed for each lattice, some information regarding the machine momentum aperture can be learned, which is shown in Table 1. Starting from 2008 dAu run with the Yellow ring for Au, the IBS (intra-beam scattering) suppression lattice with 90 degree phase advance per FODO cell is used. With stronger focusing, the tune, and the transition γ as well, are increased by 3 units. The dispersion in arcs is decreased and hence the H-function is reduced in achieving the smaller transverse emittance growth due to IBS [2].
