Comparing maternal factors associated with postpartum depression between primiparous adolescents and adults: A large retrospective cohort study.

OBJECTIVES: This study aimed to estimate the prevalence of diagnosed postpartum depression (PPD) and the likelihood of PPD among primiparous women. We also evaluated differences in the influence of various maternal factors associated with PPD in adolescent versus adult mothers. METHODS: We conducted a retrospective cohort study using electronic health records linked to birth certificates to evaluate the associations between maternal factors and PPD diagnosis. The study population was stratified into adults and adolescents based on age at delivery. We evaluated socioeconomic, demographic, psychological, and clinical factors associated with PPD in each of the age-defined maternal cohorts using multivariable logistic regression analyses. RESULTS: A total of 61,226 primiparous women, including 6435 (11%) mothers younger than 20 years old, were included in the study. The overall PPD rate was 4.0%, with the age-specific PPD rate measuring 1.6 times higher in adolescents than in adult women (6.1% vs. 3.8%). Compared with adults, adolescents were less likely to obtain firsttrimester prenatal care (33% vs. 16%), more likely to have recent tobacco use (11% vs. 6%), and more likely to have had an infection during pregnancy (5% vs. 1%). In adjusted models, significant factors for PPD in both groups included a history of depression or anxiety, tobacco use, and long-acting reversible contraception use. CONCLUSIONS: In this cohort of first-time mothers, adolescents had higher rates of PPD diagnosis as well as PPD-associated maternal factors than adults. Increased awareness of PPD risk in adolescents and early intervention, including integrating mental healthcare into prenatal care, may help benefit adolescents and reduce the risk and severity of PPD.

Cervical mucus patterns and the fertile window in women without known subfertility: a pooled analysis of three cohorts.

STUDY QUESTION: What is the normal range of cervical mucus patterns and number of days with high or moderate day-specific probability of pregnancy (if intercourse occurs on a specific day) based on cervical mucus secretion, in women without known subfertility, and how are these patterns related to parity and age? SUMMARY ANSWER: The mean days of peak type (estrogenic) mucus per cycle was 6.4, the mean number of potentially fertile days was 12.1; parous versus nulliparous, and younger nulliparous (<30 years) versus older nulliparous women had more days of peak type mucus, and more potentially fertile days in each cycle. WHAT IS KNOWN ALREADY: The rise in estrogen prior to ovulation supports the secretion of increasing quantity and estrogenic quality of cervical mucus, and the subsequent rise in progesterone after ovulation causes an abrupt decrease in mucus secretion. Cervical mucus secretion on each day correlates highly with the probability of pregnancy if intercourse occurs on that day, and overall cervical mucus quality for the cycle correlates with cycle fecundability. No prior studies have described parity and age jointly in relation to cervical mucus patterns. STUDY DESIGN, SIZE, DURATION: This study is a secondary data analysis, combining data from three cohorts of women: 'Creighton Model MultiCenter Fecundability Study' (CMFS: retrospective cohort, 1990-1996), 'Time to Pregnancy in Normal Fertility' (TTP: randomized trial, 2003-2006), and 'Creighton Model Effectiveness, Intentions, and Behaviors Assessment' (CEIBA: prospective cohort, 2009-2013). We evaluated cervical mucus patterns and estimated fertile window in 2488 ovulatory cycles of 528 women, followed for up to 1 year. PARTICIPANTS/MATERIALS, SETTING, METHODS: Participants were US or Canadian women age 18-40 years, not pregnant, and without any known subfertility. Women were trained to use a standardized protocol (the Creighton Model) for daily vulvar observation, description, and recording of cervical mucus. The mucus peak day (the last day of estrogenic quality mucus) was used as the estimated day of ovulation. We conducted dichotomous stratified analyses for cervical mucus patterns by age, parity, race, recent oral contraceptive use (within 60 days), partial breast feeding, alcohol, and smoking. Focusing on the clinical characteristics most correlated to cervical mucus patterns, linear mixed models were used to assess continuous cervical mucus parameters and generalized linear models using Poisson regression with robust variance were used to assess dichotomous outcomes, stratifying by women's parity and age, while adjusting for recent oral contraceptive use and breast feeding. MAIN RESULTS AND THE ROLE OF CHANCE: The majority of women were <30 years of age (75.4%) (median 27; IQR 24-29), non-Hispanic white (88.1%), with high socioeconomic indicators, and nulliparous (70.8%). The mean (SD) days of estrogenic (peak type) mucus per cycle (a conservative indicator of the fertile window) was 6.4 (4.2) days (median 6; IQR 4-8). The mean (SD) number of any potentially fertile days (a broader clinical indicator of the fertile window) was 12.1 (5.4) days (median 11; IQR 9-14). Taking into account recent oral contraceptive use and breastfeeding, nulliparous women age ≥30 years compared to nulliparous women age <30 years had fewer mean days of peak type mucus per cycle (5.3 versus 6.4 days, P = 0.02), and fewer potentially fertile days (11.8 versus 13.9 days, P < 0.01). Compared to nulliparous women age <30 years, the likelihood of cycles with peak type mucus ≤2 days, potentially fertile days ≤9, and cervical mucus cycle score (for estrogenic quality of mucus) ≤5.0 were significantly higher among nulliparous women age ≥30 years, 1.90 (95% confidence interval (CI) 1.18, 3.06); 1.46 (95% CI 1.12, 1.91); and 1.45 (95% CI 1.03, 2.05), respectively. Between parous women, there was little difference in mucus parameters by age. Thresholds set a priori for within-woman variability of cervical mucus parameters by cycle were examined as follows: most minus fewest days of peak type mucus >3 days (exceeded by 72% of women), most minus fewest days of non-peak type mucus >4 days (exceeded by 54% of women), greatest minus least cervical mucus cycle score >4.0 (exceeded by 73% of women), and most minus fewest potentially fertile days >8 days (found in 50% of women). Race did not have any association with cervical mucus parameters. Recent oral contraceptive use was associated with reduced cervical mucus cycle score and partial breast feeding was associated with a higher number of days of mucus (both peak type and non-peak type), consistent with prior research. Among the women for whom data were available (CEIBA and TTP), alcohol and tobacco use had minimal impact on cervical mucus parameters. LIMITATIONS, REASONS FOR CAUTION: We did not have data on some factors that may impact ovulation, hormone levels, and mucus secretion, such as physical activity and body mass index. We cannot exclude the possibility that some women had unknown subfertility or undiagnosed gynecologic disorders. Only 27 women were age 35 or older. Our study participants were geographically dispersed but relatively homogeneous with regard to race, ethnicity, income, and educational level, which may limit the generalizability of the findings. WIDER IMPLICATIONS OF THE FINDINGS: Patterns of cervical mucus secretion observed by women are an indicator of fecundity and the fertile window that are consistent with the known associations of age and parity with fecundity. The number of potentially fertile days (12 days) is likely greater than commonly assumed, while the number of days of highly estrogenic mucus (and higher probability of pregnancy) correlates with prior identifications of the fertile window (6 days). There may be substantial variability in fecundability between cycles for the same woman. Future work can use cervical mucus secretion as an indicator of fecundity and should investigate the distribution of similar cycle parameters in women with various reproductive or gynecologic pathologies. STUDY FUNDING/COMPETING INTEREST(S): Funding for the three cohorts analyzed was provided by the Robert Wood Johnson Foundation (CMFS), the Eunice Kennedy Shriver National Institute of Child Health and Human Development (TTP), and the Office of Family Planning, Office of Population Affairs, Health and Human Services (CEIBA).

Modifiable life style factors and risk for incident endometriosis.

BACKGROUND: Caffeine, alcohol, smoking and physical activity are known to alter sex steroid synthesis, which may affect hormone-dependent gynaecologic disease risk, such as endometriosis; however, few studies have assessed life style factors prior to endometriosis diagnosis. METHODS: Four hundred and seventy three women, ages 18-44 years, underwent laparoscopy or laparotomy, regardless of clinical indication, at 14 clinic sites, 2007-2009. Women with prior surgically confirmed endometriosis were excluded. Life style factors were assessed prior to surgery. Adjusted risk ratios (RR) of endometriosis by caffeine, alcohol, smoking (serum cotinine), and physical activity were estimated, adjusting for age, marital status, education, race/ethnicity, age at menarche, gravidity, BMI, study site, and other life style factors. RESULTS: There were no associations between women with endometriosis and alcohol consumption (RR 0.9, 95% CI 0.7, 1.3), caffeine consumption (RR 1.1, 95% CI 0.8, 1.5), or smoking (serum cotinine <10 vs ≥10 ng/mL; RR 1.0, 95% CI 0.7, 1.6). Similar null findings were found between endometriosis and weekly occurrences of physical activity and total walking, moderate, and vigorous activity; a modest trend was found between total daily sitting time and increased endometriosis risk. CONCLUSIONS: This study, which is unique in its capture of life style exposures prior to incident endometriosis diagnosis, largely found no association between alcohol, caffeine, smoking, and physical activity and risk of endometriosis.

Opportunities for Skin Cancer Prevention Education among Individuals Attending a Community Skin Cancer Screening in a High-Risk Catchment Area.

Despite the highly preventable nature of skin cancer, it remains the most commonly diagnosed form of cancer in the United States. Recommendations for a complete skin cancer prevention regimen include engaging in photoprotection (e.g., sunscreen use), avoiding skin cancer risk behaviors (e.g., tanning), and receiving total body skin exams from a health care provider. The current study examined reported engagement in these behaviors among participants attending a community skin cancer screening (N = 319) in a high-risk catchment area to assess the need for increased health education on skin cancer prevention. Participants' responses indicate a history of suboptimal avoidance of skin cancer risk behaviors. Over half of participants (52%) reported four or more blistering sunburns before age 20, and 46% reported indoor tanning at least one during their lifetime. There is a need among this population for education regarding a complete skin cancer prevention regimen, which could improve adherence to photoprotection and avoidance of skin cancer risk behaviors, thereby reducing morbidity and mortality due to skin cancer.

Do cancer survivors develop healthier lifestyle behaviors than the cancer-free population in the PLCO study?

BACKGROUND: Current studies report mixed results in health status and health behaviors after a diagnosis of cancer. The aim of our study is to investigate potential differences in lifestyle factors among cancer survivors and cancer-free individuals in a prospective cohort study conducted in the United States. METHODS: Using data from the Prostate, Lung, Colorectal and Ovarian (PLCO) Trial, 10,133 cancer survivors were identified and compared to 81,992 participants without cancer to evaluate differences in body mass index (BMI), smoking, NSAID use, and physical activity. RESULTS: Cancer survivors, compared to the cancer-free, were significantly less likely to engage in physical activity (odds ratio (OR) = 0.82, 95% CI = 0.77-0.88). Compared to those who were obese at baseline, cancer survivors were more likely to be at normal BMI at follow-up compared to the cancer-free (OR = 1.90, 95% CI = 1.42-2.54). Cancer survivors were less likely to report regular aspirin use as compared to the cancer-free population (OR = 0.86, 95 % CI = 0.82-0.92). Of the current smokers, cancer survivors were more likely to be former smokers at follow-up compared to the cancer-free (OR = 1.50, 95% CI = 1.30-1.74). CONCLUSION: Upon stratification by baseline health markers, cancer survivors practice healthier lifestyle habits such as smoking cessation and maintenance of a healthy weight. However, cancer survivors are less likely to be physically active as compared to cancer-free individuals, regardless of baseline practices. IMPLICATIONS FOR CANCER SURVIVORS: For cancer survivors who reported poor health status and behaviors at baseline, a cancer diagnosis may encourage the practice of healthier lifestyle behaviors.

A gender-based approach to developing a healthy lifestyle and healthy weight intervention for diverse Utah women.

Utah women from some cultural minority groups have higher overweight/obesity rates than the overall population. We utilized a gender-based mixed methods approach to learn about the underlying social, cultural and gender issues that contribute to the increased obesity risk among these women and to inform intervention development. A literature review and analysis of Utah's Behavioral Risk Factor Surveillance System data informed the development of a focus group guide. Focus groups were conducted with five groups of women: African immigrants from Burundi and Rwanda, African Americans, American Indians/Alaskan Natives, Hispanics/Latinas, and Pacific Islanders. Six common themes emerged: (1) health is multidimensional and interventions must address health in this manner; (2) limited resources and time influence health behaviors; (3) norms about healthy weight vary, with certain communities showing more preference to heavier women; (4) women and men have important but different influences on healthy lifestyle practices within households; (5) women have an influential role on the health of families; and (6) opportunities exist within each group to improve health. Seeking insights from these five groups of women helped to identify common and distinct cultural and gender themes related to obesity, which can be used to help elucidate core obesity determinants.

Preventive health care among HIV positive women in a Utah HIV/AIDS clinic: a retrospective cohort study.

BACKGROUND: Despite evidence that HIV positive women may suffer higher rates of heart disease, diabetes, human papillomavirus infection, and some types of cancer, the provision of preventive health services to HIV positive women is unknown. Preventive health services recommended for such women include breast, colorectal and cervical cancer screening, sexually transmitted infection (STI) testing, vaccinations, and patient counseling on a number of issues including sexual behaviors. METHODS: This retrospective cohort study utilized medical record reviews of 192 HIV positive women who were patients at the University of Utah Infectious Diseases Clinic in 2009. Medical records were reviewed for all encounters during 2009 using a standardized data collection form; data were collected on patient demographics and a variety of preventive health services. Chi squared tests were used to assess receipt of preventive health services by demographic factors, and multivariable logistic regression was used to determine predictors of receiving select services. RESULTS: The most commonly recorded preventive services included blood pressure screening, screening for Hepatitis A and B, Tetanus-Diphtheria-Pertussis vaccination, Pneumococcal pneumonia vaccination, substance abuse screening, and mental health screening. STI testing and safe sex counseling were documented in the medical records of only 37% and 33.9% of women, respectively. Documentation of cancer screening was also low, with cervical cancer screening documented for 56.8% of women, mammography for 65% (N = 26/40) of women, and colorectal cancer screening for 10% (N = 4/40) of women, where indicated. In multivariable models, women with private health insurance were less likely to have documented STI testing (OR 0.20; 95% CI 0.08 - 0.52), and, Hispanic women were less likely to have documented safe-sex counseling (OR 0.26; 95% CI 0.07 - 0.94). CONCLUSIONS: HIV/AIDS providers should focus on the needs of all women for preventive care services, including those with fewer socio-demographic risk factors (i.e., insured, stable housing etc.). In addition, failure to provide STI testing, cancer screening, or safe sex counseling to all patients represents a missed opportunity for provision of services that are important from both a clinical and public health perspective.

Exploring attitudes, beliefs, and communication preferences of Latino community members regarding BRCA1/2 mutation testing and preventive strategies.

PURPOSE: To inform development of a culturally sensitive hereditary breast and ovarian cancer communication initiative and related clinical genetic services. METHODS: Five focus groups were conducted with 51 female and male Latinos. Educational materials were designed to communicate information about hereditary breast or ovarian cancer and availability of relevant clinical services or prevention strategies. Focus groups explored participants' knowledge, attitudes, and beliefs about hereditary breast and ovarian cancer, BRCA1/2 testing, and communication preferences for hereditary breast and ovarian cancer health messages. RESULTS: Overall, awareness of familial breast and ovarian cancer and availability of genetic risk assessment was low. Once informed, participants held favorable attitudes toward risk assessment and counseling services. Critical themes of the research highlighted the need to provide bilingual media products and use of a variety of strategies to increase awareness about hereditary cancer risk and availability of clinical genetic services. Important barriers were identified regarding family cancer history communication and cancer prevention services. Strategies were suggested for communicating cancer genetic information to increase awareness and overcome these barriers; these included both targeted and tailored approaches. CONCLUSION: This research suggests that cancer genetic communication efforts should consider community and cultural perspectives as well as health care access issues before widespread implementation.

Cellular phone use and brain tumor: a meta-analysis.

BACKGROUND: The dramatic increase in the use of cellular phones has generated concerns about potential adverse effects, especially the development of brain tumors. We conducted a meta-analysis to examine the effect of cellular phone use on the risk of brain tumor development. METHODS: We searched the literature using MEDLINE to locate case-control studies on cellular phone use and brain tumors. Odds ratios (ORs) for overall effect and stratified ORs associated with specific brain tumors, long-term use, and analog/digital phones were calculated for each study using its original data. A pooled estimator of each OR was then calculated using a random-effects model. RESULTS: Nine case-control studies containing 5,259 cases of primary brain tumors and 12,074 controls were included. All studies reported ORs according to brain tumor subtypes, and five provided ORs on patients with > or =10 years of follow up. Pooled analysis showed an overall OR of 0.90 (95% confidence interval [CI] 0.81-0.99) for cellular phone use and brain tumor development. The pooled OR for long-term users of > or =10 years (5 studies) was 1.25 (95% CI 1.01-1.54). No increased risk was observed in analog or digital cellular phone users. CONCLUSIONS: We found no overall increased risk of brain tumors among cellular phone users. The potential elevated risk of brain tumors after long-term cellular phone use awaits confirmation by future studies.

Colorectal cancer surveillance behaviors among members of typical and attenuated FAP families.

OBJECTIVES: Although enhanced colorectal surveillance is recommended for members of familial adenomatous polyposis (FAP) families, little is known about individual-level adherence behavior. This study examined factors associated with recent use of colorectal cancer (CRC) surveillance among FAP patients and their at-risk relatives. METHODS: This cross-sectional study conducted a computer-assisted telephone survey among 150 members of 71 extended families with classic (FAP) or attenuated adenomatous polyposis (AFAP). Participants were enrolled in a university-based hereditary CRC registry or were first-degree relatives of enrollees. Both qualitative and quantitative data were collected and analyzed. RESULTS: Surveillance behavior varied by disease status. Fifty-four percent of 71 participants with a personal history of FAP and 42% of 79 at-risk relatives reported recent use of CRC surveillance recommendations. In multiple logistic regression analysis, lack of patient recall of provider recommendation for an endoscopic examination of the colon (OR 4.8, 95% CI 1.8-13.1), lack of health insurance or no reimbursement for CRC surveillance (OR 3.6, 95% CI 1.2-10.5), and/or the belief that their relative risk of CRC is not increased (OR 3.1, 95% CI 1.2-7.1) were independently associated with not having had a recent colonoscopy or sigmoidoscopy. CONCLUSIONS: Despite the known benefits of CRC surveillance, a substantial proportion of FAP family members did not have a recent colonoscopy or endoscopy. Interventions targeted at both clinicians and patients are needed to improve surveillance behavior. These data are also important in designing decision support tools to assist clinicians in identifying and managing high-risk patients.
