Objective To explore the relations between pulse pressure and LDL-C for elderly patients with hyperten-sion. Methods A total of 451 elderly patients with hypertension were selected and divided into four groups. Group A was 65 to 69 years of age, group B was 70 to74 years of age, group C was 75 to 79 years of age, and group D was ≥80 years of age. They were also divided into four groups according to PP levels: PP1 group ≤40 mm Hg, PP2 group 41 to 60 mm Hg, PP3 group 61 to 80 mm Hg, and PP4 group>80 mm Hg. They were divided into LDL-C group 1 (≥2.6 mmol/L) and LDL-C group 2 (<2.6 mmol/L) according to their LDL-C levels. Distribution of different age groups in four PP groups and the effects of different levels of LDL-C on pulse pressure were analyzed. Results (1) The propor-tions of PP2 group among the four age groups were 59.41%, 48.84%, 55.45% and 51.67%. The proportions of PP4 a-mong the four age groups were 4.95%, 3.88%, 3.96% and 7.50%. (2) Compared with PP1 group, the proportion of LDL-C ≥2.6 mmol/L in PP2 group, PP3 group and PP4 group was significantly increased. Conclusion (1) PP levels in different ages groups are concentrated on 41-60 mmHg. Among elderly patients with hypertension>80 mmHg, the pro-portion of patients with advanced age (≥years of age) is relatively higher. (2) LDL-C is the risk factor of increased pulse pressure for elderly patients with hypertension.

Objective:To investigate the awareness and attitude towards living wills among community-dwelling elderly in Taiyuan.Methods:A total of 540 residents aged 60 years or older were selected from six communities of Taiyuan city for face-to-face questionnaire survey from November 2018 to March 2019. Chi-square test and logistic regression model were used to analyze the influencing factors for awareness and attitude towards living wills.Results:The awareness rate of living wills in responders was 44.1%(226/513); and the awareness was significantly associated with age (χ 2=11.09, P=0.001), education level (χ 2=7.95, P=0.005), and daily living abilities (χ 2=8.10, P=0.017) of the residents. After the knowledge popularization, 49.9%(256/513) of responders were willing to sign the living order documents. The multivariate logistics analysis showed that residents with age of 60-74 years ( OR=2.151, 95% CI:1.380-2.941), with bachelor degree or above ( OR=3.048, 95% CI:1.571-5.913), with severely impaired activities of daily living ( OR=2.849, 95% CI:1.223-6.638), with multimorbidity ( OR=1.654, 95% CI:1.138-2.404), and with knowledge of living will ( OR=1.596, 95% CI:1.098-2.322) were more likely to sign a living will document. Conclusion:The awareness and acceptance of living wills among the community-dwelling elderly in Taiyuan city is not so high, and it is necessary to further strengthen the promotion of living wills in the city.

Objective To explore the effects of vascular risk factors on cognitive function among the elderly in community. Methods A cross-sectional study was conducted in 1 269 elderly people ( aged 65 and over) who were randomly selected from three communities. Through face-to-face interview, cognitive function was assessed by mini-mental state examination(MMSE),and blood samples were collected for labo-ratory examination. Logistic regression analysis was used to analyze the vascular risk factors affecting cogni-tive function. Results Age (( 73. 1 ± 6. 6), ( 71. 3 ± 4. 9),t=4. 603,P<0. 05),education level ( χ2=12. 727,P<0. 05),hypertension (χ2=9. 106,P<0. 05) and LDL-C (χ2=5. 157,P<0. 05) were significantly different in the elderly with or without mild cognitive impairment(MCI). After controlling age,gender and ed-ucation,the logistic regression analysis showed that hypertension(β=0. 378,P=0. 006,OR(95%CI)=1. 44 (1. 10-1. 91)),systolic blood pressure ≥140 mmHg( β=0. 350,P=0. 011,OR( 95% CI)= 1. 42( 1. 08-1. 86),1 mmHg=0. 133 kPa),and high LDL-C( β=0. 355,P=0. 014,OR(95%CI)=1. 43( 1. 08-1. 89)) were the risk factors of MCI in the elderly in the community. Hypertension alone or high LDL-C (β=0. 365, P=0. 029,OR(95%CI)=1. 44(1. 04-2. 00)) alone was risk factor for mild cognitive impairment in the eld-erly in the community. The risk of mild cognitive impairment in the elderly with hypertension and high LDL- C was 2. 00 times higher than that in the healthy elderly ( β=0. 696,P<0. 05,OR( 95%CI)= 2. 00( 1. 36-2. 97)). Conclusion Mild cognitive impairment in the elderly is closely related to hypertension and elevat-ed LDL-C levels. Multiple vascular risk factors can further increase the risk of cognitive impairment.
