The positive experience of screening quality among users of a cervical cancer detection center

BACKGROUND: Our objective was to determine the main factors associated with increased utilization of a cervical cancer screening program (CCSP) in a population with a high mortality rate due to cervical cancer. METHODS: A population-based study was carried out in the Mexican state of Morelos, Mexico. The study population included 3,197 women between the ages of 15 and 49 years who were selected at random using a State Household Sampling Framework in the State of Morelos's 33 municipalities. The sample included 2,094 women with a history of a previous Papanicolaou (Pap) test. RESULTS: A previous experience of good screening quality is strongly associated with greater use of the CCSP (OR = 4.2; 95% confidence interval [CI], 1.6-10.9). The educational level of the head of the family is related to more frequent use of Pap smear services. Women whose husbands have 13 or more years of education (OR = 1.8; 95% CI 1.1-2.9) were more likely to have been screened. Similarly, women who had used two or more family planning methods (OR = 1.6; 95% CI 1.2-2.1) and those who knew why the Pap test was given (OR = 3.0; 95% CI 2.1-4.3) had a better history of Pap screening. CONCLUSIONS: In areas where coverage of cervical cancer screening is low, a CCSP that guarantees the quality of all the different elements of care is essential if obstacles to cervical cancer prevention are to be eliminated. It is of particular importance to take into account and satisfy the perceptions and expectations of the women at risk.     

中国妇女低剂量口服避孕药使用者中脑卒中发病情况的前瞻性研究

目的 了解目前我国广泛应用的国产低剂量复方口服避孕药（COC）与脑卒中发病危险性的关系,以期降低COC的不良反应。方法 应用前瞻性队列研究的方法,于1997年7月至2000年6月在江苏太仓市和如东县25个乡镇随访比较44408名使用甾体激素避孕药（HC）和75230名使用IUD妇女的脑卒中发病率。结果 （1）HC队列出血型脑卒中的调整后发病率为34．74／10万,是IUD队列的2．72倍（P＜0．01）;HC队列45岁以下妇女出血型脑卒中的发病率明显高于IUD队列;停用HC10年以上者出血型脑卒中发病危险度为2．17（1．16,4．06）,仍显著高于IUD使用者。（2）国产低剂量COC当前使用者中出血型脑卒中发病危险性为非使用者3．60倍（1．73,7．53）,停用5年以内发病危险度达3．09（1．26,7．57）,但停用5年以后发病危险度明显下降。（3）在国产COC当前使用者中未发现梗塞型脑卒中发病率明显升高现象。（4）在国产低剂量COC使用者中,高血压可能是出血型脑卒中最重要的危险性因素。（4）在国产低剂量COC使用者中,高血压可能是出血型脑卒中最重要的危险性因素。结论 使用国产低剂量COC的妇女出血型脑卒中发病危险性明显升高,其对出血型脑卒中发病的影响可持续到停用以后,应进一步研究COC与高血压对出血型脑卒中发病的影响。     

High risk health behaviours among adult Jamaicans

The purpose of this study was to assess the prevalence of high risk health behaviours among adult Jamaicans aged 15-49 years in 2000, and to compare the results with the 1993 survey. A nationally representative sample of 2013 persons aged 15-74 years was surveyed in 2000 using cluster sampling in the Jamaica Healthy Lifestyle Survey (Wilks et al, unpublished). Interviewer administered questionnaires and anthropometrical measurements were done. Data for a sub-sample of adults aged 15-49 years were analyzed The sub-sample included 1401 persons (473 men and 928 women). Significantly more men (18.6%) than women (4.3%) reported never having had a blood pressure check (p = 0.0001). Approximately one-third of the women reported that they had never had a Pap smear (36.0%) or a breast examination (31.2%). Current cigarette smoking was reported in 28.6% of men and 7.7% of women (OR 3.73 CI 2.71, 5.15), while 49.0% of men and 15.0% of women ever smoked marijuana (OR 3.28 CI 2.56, 4.20). Significantly more men (28.0%) than women (11.7%) reported ever having a sexually transmitted disease (OR 2.93 CI 2.16, 3.97); having more than one sexual partner in the past year (49.1% vs 11.4%, OR 4.31 CI 3.22, 5.76) and usually using a condom during sexual intercourse (55.3% vs 40.5%, OR 1.3 CI 1.11, 1.68). Between 1993 and 2000, significant trends include: more persons reported having a blood pressure check, a reduction in multiple sexual partners, increased condom use at last sex (women), reduced crack/cocaine use (males) and increased marijuana smoking. Although there were some significant positive lifestyle trends between 1993 and 2000, high risk behaviours remain common among Jamaican adults. Comprehensive health promotion programmes are needed to address these risk behaviours.     

Characteristics of respondents to a cervical cancer screening program in a developing country

BACKGROUND: Characteristics associated with the response to a personalized, mailed invitation for the Papanicolaou (Pap) test vary among women. This study assesses the relationship between selected characteristics (e.g., demographic, obstetric, Pap history) and the response to a letter of invitation to undergo a Pap test among Mexican women affiliated with the Mexican Social Security Institute (IMSS). METHODS: Study subjects were 328 women affiliated with the IMSS who received and responded to a mailed letter of invitation, and 247 age- and clinically matched controls who received but did not respond to the letter of invitation. Statistical analysis consisted of multivariate conditional regression model. RESULTS: Having better housing conditions was one of the factors associated with letter response (medium level vs. low level, odds ratio [OR] = 3.17, 95% confidence interval [95% CI] = 2.46-4.09; high level vs. low level, OR = 2.65, 95% CI = 2.06-3.41). Other factors positively associated with letter response were greater number of pregnancies, previous Pap testing, being pleased at receipt of the letter of invitation, and knowing another woman who had received the invitation. Factors associated negatively to letter response were 7 or more years of formal education (> or =7 years vs. 0-6 years, OR = 0.50, 95% CI = 0.40-0.63), having a current job, availability of other medical services in addition to the IMSS, and willingness to receive Pap results by mail. CONCLUSIONS: Low educational level is not a limitation for cervical cancer screening call and recall among women affiliated with the IMSS.     

Forty years of combined oral contraception: the evolution of a revolution

The combined oral contraceptive (COC) pill has become an integral part of fertility choice in almost every country since its introduction in 1960 in the United States. It was the first contraceptive method to provide sexual freedom of choice for women through reliable personal, private control of fertility. Modern, very low-dose pills have maintained a high degree of contraceptive efficacy, but the margin for error in pill-taking appears much smaller. These COCs have a much lower incidence of side effects and serious complications than early high-dose COCs. Serious health risks from venous thromboembolism are rare, and not measurably higher for pills containing third-generation compared with earlier progestogens. Most women feel very well taking modern COCs, but myths about these drugs still abound. Most non-contraceptive health benefits of COCs are still not widely appreciated in spite of much evidence. Controversy still persists over the association between COC use and breast cancer. Although slightly more breast cancers are detected in current COC users (relative risk 1.24; 95% CI, 1.15-1.33), they are less advanced and less aggressive. Some women have pre-existing medical risk factors for COC use, and a detailed history for cardiovascular risk factors is one of the most important precautions.

Identifying women with cervical neoplasia: using human papillomavirus DNA testing for equivocal Papanicolaou results

CONTEXT: A Papanicolaou (Pap) test result of atypical squamous cells of undetermined significance (ASCUS) presents a clinical challenge. Only 5% to 10% of women with ASCUS harbor serious cervical disease, but more than one third of the high-grade squamous intraepithelial lesions (HSILs) in screening populations are identified from ASCUS Pap test results. OBJECTIVE: To determine whether human papillomavirus (HPV) DNA testing of residual material from liquid-based Pap tests and referral of cases found to be HPV-positive directly to colposcopy could provide sensitive detection of underlying HSILs in women with ASCUS Pap results, compared with repeat Pap testing. DESIGN AND SETTING: Natural history of women with ASCUS Pap smear results, all of whom had liquid-based cytology, HPV testing, and subsequent repeat Pap tests and colposcopy with histologic evaluation, conducted at 12 gynecology clinics in a large managed care organization between October 1995 and June 1996. PARTICIPANTS: From a cohort of 46009 women who had routine cervical examinations, 995 women with Pap test results of ASCUS who consented to participate were identified. MAIN OUTCOME MEASURES: Cervical histology, HPV test results, and repeat Pap smear results, and sensitivity of HPV testing to identify patients found to have HSIL+ histology. RESULTS: Of 995 participants with ASCUS Pap test results, 973 had both a definitive histologic diagnosis and HPV result. Sixty-five (6.7%) had histologic HSIL or cancer. For women with histologic HSIL+, the HPV test was positive in 89.2% (95% confidence interval [CI], 78.4%-95.2%), and the specificity was 64.1 % (95% CI, 60.9%-67.2%). The repeat Pap smear result was abnormal in 76.2% (95% CI, 63.5%-85.7%). Triage based on HPV testing only or on repeat Pap testing only would refer similar proportions (approximately 39%) to colposcopy. The sensitivity of HPV DNA testing for HSIL was equivalent to, if not greater than, that of the repeat Pap test. We further estimated that an HPV-based algorithm including the immediate colposcopy of HPV-positive women, and then repeat Pap testing of all others, would provide an overall sensitivity of 96.9% (95% CI, 88.3%-99.5%). CONCLUSIONS: For women with ASCUS Pap tests, HPV DNA testing of residual specimens collected for routine cervical cytology can help identify those who have underlying HSIL. By testing the specimen collected at initial screening, the majority of high-risk cases can be identified and referred for colposcopy based on a single screening.     

Periconceptional Folic Acid Supplementation in Chinese Women: A Cross-sectional Study

Objective To investigate the status of folic acid (FA) supplementation and determinants of its use inpregnant Chinese women Methods In this cross-sectional study, questionnaires were used to collect information of participantsand FA supplementation. Women were recruited between 6 and 12 weeks postpartum in Tianjin, China,between July 2015 and July 2016 Results A total of 1,921 women were recruited in the study. Approximately 93.1% of the studyparticipants used FA, while 14.4% of the women taking FA from three months prior to preconception tothree months post-conception. Women who took FA for three months prior to preconception throughat least three months into their pregnancy were more likely to be between 30 and 34 years old (OR =2.91, 95% CI: 1.15, 7.33), employed (OR = 2.07, 95% CI: 1.17, 3.67), primigravida (OR = 5.20, 95% CI:3.02, 8.96), married to spouses with an intermediate education level (OR = 2.92, 95% CI: 1.45, 5.89), andearn a high family income (OR = 3.19, 95% CI: 1.57, 6.49) Conclusion The prevalence of periconceptional FA intake was far below the requirements of theNational Health and Family Planning Commission of China; therefore, knowledge of FA supplementationshould be strengthened among women who are or planning to become pregnant.     

Oral contraceptives and cervical cancer risk in Costa Rica. Detection bias or causal association?

To examine the relationship between cervical cancer and oral contraceptive (OC) use, we analyzed data from a population-based, case-control study in Costa Rica. Women aged 25 to 58 years in whom cervical cancer was diagnosed and reported to the National Tumor Registry were examined as two separate case groups: invasive cervical cancer and carcinoma in situ (CIS). Controls were women aged 25 to 58 years identified through a national survey. Women who had used OCs had no increased risk of invasive cervical cancer compared with women who had never used OCs (relative risk, 0.8; 95% confidence interval, 0.5 to 1.3). Women who had used OCs had an increased risk of CIS compared with those who had never used OCs (relative risk, 1.6; 95% confidence interval, 1.2 to 2.2). However, further analyses indicated that this increased risk was confined to those who had recently used OCs. Also, the risk of CIS was not elevated in subgroups in which a history of cervical smears was not strongly linked to OC use. The elevated risk of CIS among OC users may therefore reflect a bias caused by enhanced detection of disease rather than a causal association.     

Dating violence against adolescent girls and associated substance use, unhealthy weight control, sexual risk behavior, pregnancy, and suicidality

CONTEXT: Intimate partner violence against women is a major public health concern. Research among adults has shown that younger age is a consistent risk factor for experiencing and perpetrating intimate partner violence. However, no representative epidemiologic studies of lifetime prevalence of dating violence among adolescents have been conducted. OBJECTIVE: To assess lifetime prevalence of physical and sexual violence from dating partners among adolescent girls and associations of these forms of violence with specific health risks. DESIGN, SETTING, AND PARTICIPANTS: Female 9th through 12th-grade students who participated in the 1997 and 1999 Massachusetts Youth Risk Behavior Surveys (n = 1977 and 2186, respectively). MAIN OUTCOME MEASURES: Lifetime prevalence rates of physical and sexual dating violence and whether such violence is independently associated with substance use, unhealthy weight control, sexual risk behavior, pregnancy, and suicidality. RESULTS: Approximately 1 in 5 female students (20.2% in 1997 and 18.0% in 1999) reported being physically and/or sexually abused by a dating partner. After controlling for the effects of potentially confounding demographics and risk behaviors, data from both surveys indicate that physical and sexual dating violence against adolescent girls is associated with increased risk of substance use (eg, cocaine use for 1997, odds ratio [OR], 4.7; 95% confidence interval [CI], 2.3-9.6; for 1999, OR, 3.4; 95% CI, 1.7-6.7), unhealthy weight control behaviors (eg, use of laxatives and/or vomiting [for 1997, OR, 3.2; 95% CI, 1.8-5.5; for 1999, OR, 3.7; 95% CI, 2.2-6.5]), sexual risk behaviors (eg, first intercourse before age 15 years [for 1997, OR, 8.2; 95% CI, 5.1-13.4; for 1999, OR, 2.4; 95% CI, 1.4-4.2]), pregnancy (for 1997, OR, 6.3; 95% CI, 3.4-11.7; for 1999, OR, 3.9; 95% CI, 1.9-7.8), and suicidality (eg, attempted suicide [for 1997, OR, 7.6; 95% CI, 4.7-12.3; for 1999, OR, 8.6; 95% CI, 5.2-14.4]). CONCLUSION: Dating violence is extremely prevalent among this population, and adolescent girls who report a history of experiencing dating violence are more likely to exhibit other serious health risk behaviors.     

Screening for Chlamydia trachomatis at the time of routine Pap smear in general practice: a cluster randomised controlled trial

OBJECTIVE: To determine whether asking general practitioners to offer chlamydia screening at the same time as Pap screening increases chlamydia screening rates. DESIGN: A pragmatic cluster randomised controlled trial. PARTICIPANTS AND SETTING: Doctors from 31 general practices in the Australian Capital Territory performing more than 15 Pap smear screens per year, and all women aged 16-39 years attending those practitioners between 1 November 2004 and 31 October 2005. INTERVENTION: Doctors in the intervention practices were asked to routinely offer combined chlamydia and Pap screening to eligible women; doctors in the control practices were asked to implement screening guidelines based on a risk assessment of the individual patient (ie, usual practice). MAIN OUTCOME MEASURE: Chlamydia screening rate per visit. RESULTS: There were 26 876 visits by eligible women during the study period: 16 082 to intervention practices and 10 794 to control practices. Chlamydia screening occurred during 6.9% (95% CI, 6.5%-7.3%) of visits to intervention practices and 4.5% (95% CI, 4.1%-4.9%) of visits to control practices. After controlling for clustering and potential confounders, there were twofold greater odds of chlamydia screening occurring during a visit by an eligible woman to an intervention practice than to a control practice (adjusted odds ratio, 2.1 [95% CI, 1.3-3.4]). CONCLUSION: Combining chlamydia and Pap screening increases the rate of chlamydia screening in general practice. Implementing this approach would require little additional infrastructure support in settings where a cervical screening program already exists.     

Health-related attitudes and risk factors for sexually transmitted infections of Chinese women who have sex with women

Background  Previous studies have shown evidence of health-related risk behaviors among women who have sex with women (WSW), such as sex with men, multiple bisexual partners, and drug use. Women who have sex with women have also been known to avoid routine physical examinations and conceal their same-sex history from physicians, which can affect their ability to receive an accurate diagnosis and treatment. No previous research has targeted women who have sex with women in China. We sought to describe women who have sex with women in China and explore risk factors for their reproductive tract infections (RTI)/sexually transmitted infections (STI).

Methods  Participants were recruited through outreach in venues and online for a cross-sectional study. Data was collected using interviews and laboratory tests.

Results  We recruited 224 women who have sex with women. In the year preceding their participation in the study, 92% (206/224) of women reported sexual relations with women. The RTI rates were: gonorrhea (15.8%), Chlamydia (3.5%), syphilis (0.5%), bacterial vaginosis (BV) (14.4%), hepatitis B virus (HBV) (0.9%), hepatitis C virus (HCV) (0.5%), and candidiasis (6.9%). No HIV or herpes simplex virus (HSV) positive cases were detected. Factors associated with gonorrhea infection were non-Beijing local residency [odds ratio (OR)=2.1, 95% confidence interval (CI): 1.2 to 3.8] and genital-genital contact (OR=3.1, 95% CI: 1.3 to 7.2); factors associated with curable STI (excluding BV, candidiasis, HBV and HCV) were non-Beijing local residency (OR=1.9; 95% CI: 1.2 to 3.0) and bleeding during or after sex (OR=18.1; 95% CI: 5.2 to 62.6); and the factor associated with RTI (including all the infections tested) was bleeding during or after sex (OR=37.8, 95% CI: 11.2 to 127.4).

Conclusions  Behaviors that may cause RTI/STI exist among Chinese women who have sex with women. Researchers should consider these behaviors when planning corresponding prevention and interventions.

     

Prevalence of risk factors associated with human papillomavirus infection in women living with HIV

BACKGROUND: Concurrent infection with HIV and human papillomavirus (HPV) in women is associated with increased rates of cervical dysplasia and shorter survival following the development of cervical cancer. The authors examined risk factors for HPV infection at study entry in HIV-positive women enrolled in the Canadian Women's HIV Study, a prospective open cohort study. METHODS: Subjects eligible for this analysis included the 375 HIV-positive women in the Canadian Women's HIV Study for whom HPV test results were available. Questionnaires on behavioural and clinical information, Pap smears, cervicovaginal lavage specimens and vaginal tampon specimens for HPV detection and typing by polymerase chain reaction were obtained at study entry. RESULTS: Overall, 67.2% (252/375) of the women were HPV-positive; the global prevalence of intermediate- and high-risk oncogenic HPV types was 49.1% (184/375). Women with squamous cell dysplasia (32/294) were more likely to have HPV infection than those without dysplasia (90.6% v. 62.6%; p = 0.002). Multivariate logistic regression analysis, with adjustment for number of lifetime partners and history of STD, revealed that the following risk factors were independently associated with HPV infection: CD4 count of less than 0.20 x 10(9)/L (adjusted odds ratio [OR] 1.99 [95% confidence interval (Cl) 1.17-3.37 (p = 0.011)]), non-white race (adjusted OR 2.00 [95% Cl 1.17-3.42 (p = 0.011)]), inconsistent condom use in the 6 months before study entry (adjusted OR 2.02 [95% Cl 1.16-3.50 (p = 0.013)]), and lower age, with women age 30-39 years (adjusted OR 0.51 [95% Cl 0.30-0.87 (p = 0.013)]) and age 40 years or older (adjusted OR 0.52 [95% Cl 0.26-1.01 (p = 0.052)]) compared with women less than 30 years of age. INTERPRETATION: Close monitoring for HPV-related effects is warranted in all HIV-positive women, particularly younger, non-white women who do not always use condoms. Counselling for women living with HIV, particularly younger women, should emphasize the importance of regular cytological screening, with increasing frequency as the CD4 count falls.     

Effect of breast self-examination techniques on the risk of death from breast cancer

OBJECTIVE: To measure the effect of breast self-examination (BSE) technique and frequency on the risk of death from breast cancer. DESIGN: Case-control study nested within the Canadian National Breast Screening Study (NBSS). SETTING: The Canadian NBSS, a multicentre randomized controlled trial of screening for breast cancer in Canadian women. SUBJECTS: The case subjects were 163 women who had died from breast cancer and 57 women with distant metastases. Ten control subjects matched by 5-year age group, screening centre, year of enrolment and random allocation group were randomly selected for each case subject. EXPOSURE MEASURES: Self-reported BSE frequency before enrolment in the NBSS, annual self-reports of BSE frequency during the program and annual objective assessments of BSE technique. OUTCOME MEASURES: Odds ratios (ORs) associated with BSE practice were estimated by conditional multiple logistic regression modelling, which permitted control of covariates. RESULTS: Relative to women who, when assessed 2 years before diagnosis, examined their breasts visually, used their finger pads for palpation and examined with their 3 middle fingers, the OR for death from breast cancer or distant metastatic disease for women who omitted 1, 2 or 3 of these components was 2.20 (95% confidence interval [CI] 1.30 to 3.71, p = 0.003). The OR for women who omitted 1 of the 3 components was 1.82 (95% CI 1.00 to 3.29, p = 0.05), for those who omitted 2 of the 3 components, 2.84 (95% CI 1.44 to 5.59, p = 0.003), and for those who omitted all 3 components, 2.95 (95% CI 1.19 to 7.30, p = 0.02). The results remained unchanged after adjustment for potential confounders. CONCLUSION: The results, obtained with the use of prospectively collected data, suggest that the performance of specific BSE components may reduce the risk of death from breast cancer.     

Chlamydia trachomatis cervical infection: prevalence and determinants among women presenting for routine gynecologic examination.

OBJECTIVE: To determine the prevalence of and risk indicators for Chlamydia trachomatis cervical infection among women presenting for a periodic medical examination. DESIGN: Prevalence study. SETTING: Centre local de services communautaires (CLSC) Saint-Louis du Parc, Montreal. PATIENTS: All women presenting for a routine gynecologic examination from May 1985 to July 1986. Of the 773 (99%) who agreed to participate 56 were excluded because of inadequate diagnostic tests (34), antibiotic intake in the preceding 6 weeks (19) or loss to follow-up after the initial visit (3). OUTCOME MEASURES: Culture was the diagnostic standard, but rapid diagnostic tests were also used. From the identified cases logistic regression analysis was used to evaluate the following risk indicators: age, place of residence, use of oral contraceptives, sexual partners and frequency, history of sexually transmitted disease (STD) and abnormalities found on genital examination. MAIN RESULTS: Fifty-one of the women were found to have C. trachomatis infection, for a prevalence rate of 7.1%; 32 (63%) were completely asymptomatic. Three independent indicators were found: age of 25 years or less (odds ratio [OR] 3.2, 95% confidence limits [CL] 1.8 and 5.9), cervical erythema, contact bleeding or mucopurulent exudate (OR 2.5, 95% CL 1.4 and 4.5) and residency in the CLSC area (OR 2.3, 95% CL 1.1 and 5.1). A history of STD or vaginitis had a significant protective effect in women 30 years of age or more (OR 0.2). CONCLUSIONS: Case-finding for chlamydial infection could be an effective public health measure among women 25 years of age or less and among those with signs of cervicitis when they present for a Papanicolaou test.     

Risk factors for interstitial cystitis/painful bladder syndrome in patients with lower urinary tract symptoms: a Chinese multi-center study

Background Despite 100 years of research, the continued absence of well-established risk factors impedes the diagnosis and treatment of interstitial cystitis/painful bladder syndrome （IC/PBS）. We aimed to identify risk factors in patients with lower urinary tract symptoms （LUTS） without urinary tract infection or benign prostate hyperplasia in China.Methods A total of 397 outpatients with LUTS presenting for care to urology clinics in several hospitals throughout China were surveyed using a standardized questionnaire and validated outcome measures. The definitions for painful bladder syndrome based on the O‘Leary-Sant interstitial cystitis symptom and problem indices were used. The prevalence of possible risk factors was analyzed using the Fisher＇s exact test and Pearson chi-square test, and multivariate predictive models were developed using binary Logistic regression methods.Results Of those multi-centre patients surveyed, including 174 women and 223 men, 41% （162/397） met criteria for painful bladder syndrome. There was a significant difference between women and men （55% （95/174） vs. 30% （67/223）,P 〈0.001）. Women with IC/PBS were more likely than those without IC/PBS to report a history of gynecological infections （odds ratio （OR）： 2.85; 95% confidence interval （CI）： 1.32-6.16, P=0.007）, intake of stimulatory foods （OR： 3.52; 95% CI：1.50-8.30; P=0.004）, irritable bowel （OR： 3.46; 95% CI： 1.22-9.80; P=0.014） and/or anorectal disease （OR： 2.68; 95% CI：1.12-6.40, P=0.023）. After adjusting for confounding factors, bladder pain was significantly associated with stimulatory foods （OR： 3.85; 95% CI： 1.58-9.36, P=0.003） and anorectal disease （OR： 2.76; 95% CI： 1.09-7.04, P=0.03） in women.Caffeine beverage intake （OR： 3.54; 95% CI： 1.54-8.12, P=0.003） was identified the only modifiable association noted in multivariate analysis of men.Conclusions We found that stimutatory foods, anorectal disease and caffeine beverages are potential risk factors for IC/PBS. Further studies are necessary to determine their role in the pathogenesis of this disorder.     

Associations among condom use, sexual behavior, and knowledge about HIV/AIDS. A study of 13,293 public school students

BACKGROUND: This school-based study explored associations between Mexican young people's condom use, other sexual behaviors, and HIV/AIDS knowledge. METHODS: Students (n=13,293, 11-24 years of age) from a random sample of public schools in the central Mexican state of Morelos completed a self-administered questionnaire. We performed logistic regression analysis of condom use and sexual behavior variables and a knowledge-based index on HIV/AIDS prevention and transmission. RESULTS: Average age at sexual debut was 13.6 +/- 1.9 years among young men and 14.2 +/- 2.2 years among young women; 34.5% of sample participants reported using condoms during their first sexual intercourse. More students had intermediate HIV/AIDS knowledge levels (46%, 95% confidence interval [95% CI], 45.2-46.9) than high levels (37%, 95% CI 36.2-37.8, p <0.01). Students knew more concerning HIV transmission than about prevention of HIV infection. Among young men, high levels of HIV/AIDS knowledge increased likelihood of condom use (odds ratio [OR] 1.4, 95% CI, 1.1-1.7), while among young women high levels of knowledge decreased likelihood of using condoms (OR 0.7, 95% CI, 0.5-1.0). Young men with high levels of HIV/AIDS knowledge were more likely to have had three or more sexual partners (OR 1.7, 95% CI, 1.3-2.2), but young women with high knowledge levels were more likely to have only one lifetime sexual partner (OR 0.6, 95% CI, 0.4-0.9). CONCLUSIONS: As in previous studies in smaller samples, levels of knowledge with regard to HIV/AIDS were low in Mexican youth. HIV/AIDS education programs for Mexican students should focus on conveying knowledge on HIV prevention. Because apparently knowledge is not directly correlated with condom use among young women, prevention strategies that deal with social acceptability of condoms and social skills related with condom negotiation are also needed.     

我国围绝经期女性抑郁症状变化及影响因素分析：基于CHARLS面板数据

目的 了解我国围绝经期女性抑郁症状变化情况及影响因素,从而为制定防治策略提供依据。方法 利用CHARLS数据选取年龄45~60岁关键变量值完整的围绝经期女性作为调查对象,去除缺失值,得出4年的截面数据,分别为4318、4200、3930和4147份。通过截面数据匹配面板数据,得到4期完整的追踪数据5040份,构成n=1260,T=4的平衡短面板数据集。利用面板数据分析围绝经期女性抑郁症状检出率及变动情况,采用面板二值选择模型的随机效应Logistic回归模型分析围绝经期女性抑郁症状的影响因素。结果 不同年份追踪样本的围绝经期女性的抑郁症状检出率分别为35.9%,33.1%,36.7%,43.7%,追踪数据检出率的变化趋势不具有统计学意义（APC=3.25%,P=0.183）。回归结果显示：城镇地区OR=0.570（0.457,0.710）、文化程度越高 OR=0.759（0.655,0.879）、有配偶 OR=0.363（0.236,0.558）是围绝经期女性抑郁症状的保护因素;自评健康差 OR=2.704（2.152,3.396）、有残疾 OR=1.457（1.087,1.954）、有慢性疾病 OR=1.407（1.179,1.680）、最近两年有摔倒 OR=2.028（1.613,2.550）、睡眠时长不正常OR=2.249（1.898,2.664）、生活较不满意OR=4.803（3.757,6.140）是围绝经期女性抑郁症状的危险因素。结论 我国围绝经期女性抑郁症状检出水平较高,应加强对农村地区,文化程度低,无配偶,自评健康差,有残疾,有慢性疾病,最近两年有摔倒,睡眠时长不正常,生活较不满意等人群的心理保健和控制措施。
