生殖相关疾病与膳食炎症指数关系的研究进展

炎症参与了多囊卵巢综合征、子宫内膜异位症、妇科肿瘤等多种疾病的发生、发展,同时也可影响男性生殖功能。饮食在调节慢性炎症中发挥重要作用。膳食炎症指数（dietary inflammation index,DII）是一种新的临床膳食评估工具,将饮食分为促炎饮食和抗炎饮食,用于评估个人膳食整体的炎症潜力。研究显示,促炎饮食与生殖相关疾病的发生风险增加有关,抗炎饮食则与生殖相关疾病的发生风险降低有关。促炎饮食及其组分可升高机体内的炎症水平,促使慢性子宫内膜炎、多囊卵巢综合征、卵巢癌及子宫内膜癌等多种疾病的发生,也可对男性精子浓度和总活力等产生影响,从而导致不孕不育。综述DII与生殖相关疾病的关系和临床机制,并从疾病的预防和控制方面提出饮食建议,以期为临床治疗和护理提供参考。     

Diet Quality as Measured by the Healthy Eating Index 2015 and Oral and Pharyngeal Cancer Risk

BackgroundAlcohol and tobacco are the major risk factors for oral and pharyngeal cancer, but diet is likely to have a role, too.ObjectiveThe objective was to analyze the relationship between adherence to the 2015-2020 Dietary Guidelines for Americans (DGA), as measured by the Healthy Eating Index 2015 (HEI-2015), and oral and pharyngeal cancer risk. Moreover, this work aimed to quantify the number of avoidable cases under different scenarios of increased adherence to the DGA, with the use of the potential impact fraction. This estimates the proportion of cases that would occur if the distribution of the risk factor in the population followed an alternative distribution.DesignA multicenter, case–control study was conducted in Italy between 1991 and 2009. Participants’ usual diet for the 2 years preceding study enrolment was assessed using a food frequency questionnaire.Participants and settingCases were 946 patients admitted to major hospitals with incident, histologically confirmed oral and pharyngeal cancer. Controls were 2,492 patients admitted to the same hospitals for acute non neoplastic conditions.Main outcome measuresThe adherence to the DGA was assessed using the HEI-2015 score (range = 0 to 100), based on 13 components. The outcome was oral and pharyngeal cancer.Statistical analyses performedOdds ratios and the corresponding 95% CIs were estimated using multiple logistic regression models adjusted for tobacco, alcohol, and other relevant covariates. The potential impact fraction was estimated under different scenarios of adherence to the DGA.ResultsIn this Italian population the HEI-2015 score ranged from 33.4 to 97.5. A higher HEI-2015 score was associated with a lower risk of oral and pharyngeal cancer, with an odds ratio of 0.70 (95% CI 0.62 to 0.79) for a 10-point increment of the score. The estimated potential impact fraction was 64.8% under the maximum achievable reduction scenario, and it ranged from 9% to 27% following other more feasible scenarios.ConclusionsThe HEI-2015 score was inversely related to oral and pharyngeal cancer risk in this Italian population. This analysis allowed for the estimation of the fraction of preventable cases, under different feasible scenarios. A share of 9% to 27% of avoidable cases of oral and pharyngeal cancer might be obtained across real-world scenarios of adherence to the DGA as measured by the HEI-2015 score.     

Incorporating the Dietary Guidelines for Americans Vegetable Recommendations into the Diet Alters Dietary Intake Patterns of Other Foods and Improves Diet Quality in Adults with Overweight and Obesity

BackgroundUnderstanding how vegetables are incorporated into the diet, especially in the types and amounts recommended by the Dietary Guidelines for Americans, and how this alters dietary intake patterns is vital for developing targeted behavior change interventions.ObjectiveTo determine how a provision of vegetables was incorporated into the diet of adults with overweight and obesity; whether or not the provided vegetables displaced other foods; and what, if any, effect this had on diet quality and body weight and composition.DesignThis study investigated secondary outcomes from the Motivating Value of Vegetables Study, a community-based, randomized, parallel, nonblinded controlled trial. Participants were randomly assigned to a provided vegetable intervention or attention control group using a one to one allocation ratio.Participants/settingMen and women with self-reported low vegetable consumption, aged 18 to 65 years, with a body mass index ≥25 were recruited from Grand Forks, ND, between October 2015 and September 2017. Only participants randomized to the provided vegetable intervention group (n = 51; attrition = 8%) were included in this secondary analysis.InterventionDietary Guidelines for Americans recommended types and amounts of vegetables were provided weekly for 8 weeks.Main outcome measuresHow the provided vegetables were incorporated into the diet was measured using daily self-report and 24-hour dietary recalls. Diet quality was assessed via the Healthy Eating Index 2015. Body weight and composition were measured before and after the intervention.Statistical analyses performedData were assessed using generalized linear mixed models where phase (pre, post) was the within-subject factor and subject was the random effect.ResultsParticipants self-reported using 29% of the provided vegetables as substitutes for other foods. With the increase in vegetable consumption, there were decreases in total grains (mean difference ± standard deviation; –0.97 ± 3.23 oz-equivalents; P = 0.02), protein foods (–1.24 ± 3.86 oz-equivalents; P = 0.01), saturated fats (–6.44 ± 19.63 g; P = 0.02), and added sugars (–2.44 ± 6.78 tsp-equivalents; P = 0.02) consumed. Total Healthy Eating Index 2015 scores increased (+4.48 ± 9.63; P = 0.001) and dietary energy density decreased (–0.44 ± 0.52 kcal/g; P < 0.0001). There was no change in total energy intake or body weight and composition.ConclusionsIncreasing vegetable consumption to meet Dietary Guidelines for Americans recommendations alters dietary intake patterns, improving diet quality and energy density. These findings highlight the importance of characterizing how individuals incorporate Dietary Guidelines for Americans recommendations into their diet.     

上海市居民期望寿命与健康期望寿命的差异分析

目的 分析不同年龄、性别的上海市居民期望寿命和健康期望寿命的差异。方法 分析比较上海市和全球长寿国家/地区期望寿命的变化趋势;利用全球疾病负担研究建立的疾病和健康结局的失能权重,应用Sullivan法测算上海市居民健康期望寿命,并分析不同年龄、性别人群的健康寿命损失。结果 近40年,上海市期望寿命增长了10.86岁,2016年上海市居民期望寿命为83.18岁,其中男性80.83岁,女性85.61岁。健康期望寿命为69.46岁,其中男性为68.68岁,女性为70.23岁;与期望寿命的差距分别为13.72、12.15和15.38岁;分别占期望寿命的16.49%、15.02%和17.97%。与期望寿命相同,各年龄组女性的健康期望寿命均高于男性,平均差距为1.76岁,两者差距在20~24岁组最小为1.36岁,70~74岁组最大为2.24岁。健康期望寿命损失率随着年龄的上升而上升,<65岁女性高于男性,≥65岁则相反。结论 上海市期望寿命已达世界领先水平,但健康寿命损失较大,需要在降低死亡率的基础上进一步提高寿命质量,尤其是女性和≥65岁男性是重点关注人群。     

Older adults' vaccine hesitancy: Psychosocial factors associated with influenza,pneumococcal, and shingles vaccine uptake

Influenza, pneumococcal disease, and shingles (herpes zoster) are more prevalent in older people. These illnesses are preventable via vaccination, but uptake is low and decreasing. Little research has focused on understanding the psychosocial reasons behind older adults’ hesitancy towards different vaccines. A cross-sectional survey with 372 UK-based adults aged 65–92 years (M = 70.5) assessed awareness and uptake of the influenza, pneumococcal, and shingles vaccines. Participants provided health and socio-demographic data and completed two scales measuring the psychosocial factors associated with vaccination behaviour. Self-reported daily functioning, cognitive difficulties, and social support were also assessed. Participants were additionally given the opportunity to provide free text responses outlining up to three main reasons for their vaccination decisions. We found that considerably more participants had received the influenza vaccine in the last 12 months (83.6%), relative to having ever received the pneumococcal (60.2%) and shingles vaccines (58.9%). Participants were more aware of their eligibility for the influenza vaccine, and were more likely to have been offered it. Multivariate logistic regression analyses showed that a lower sense of collective responsibility independently predicted lack of uptake of all three vaccines. Greater calculation of disease and vaccination risk, and preference for natural immunity, also predicted not getting the influenza vaccine. For both the pneumococcal and shingles vaccines, concerns about profiteering further predicted lack of uptake. Analysis of the qualitative responses highlighted that participants vaccinated to protect their own health and that of others. Our findings suggest that interventions targeted towards older adults would benefit from being vaccine-specific and that they should emphasise disease risks and vaccine benefits for the individual, as well as the benefits of vaccination for the wider community. These findings can help inform intervention development aimed at increasing vaccination uptake in future.

正气辨析

正气属中医学的气学范围,是一身之气或人气相对邪气时的称谓,是指人体内具有抗病、祛邪、调节、修复等作用的一类细微物质;正气以其运动而发挥防御、调节、修复等作用,具有物质运动的自然科学属性。正气分布到腑腑经络,则为脏腑经络之气;分布到脉之内外,则为营气和卫气。脏腑经络之气和营卫之气的防御、修复和调节作用,可因其构成成分和所在部位的不同而有所区别,但都是正气的功能体现。
