HPV Vaccine Misperceptions Among Hispanics/Latinos in Southern California. J Racial Ethn Health Disparities 2024; 11:1557-1563. [PMID: 37195591 PMCID: PMC10191090 DOI: 10.1007/s40615-023-01631-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 04/20/2023] [Accepted: 05/04/2023] [Indexed: 05/18/2023]
Abstract
BACKGROUND Cervical and other vaccine-preventable HPV-associated cancers disproportionately impact Hispanic/Latinos in the USA. HPV vaccine uptake may be impacted by community agreement with common HPV vaccine misperceptions. It is unknown whether Hispanics/Latinos have a greater agreement with these misperceptions relative to non-Hispanic whites. METHODS HPV vaccine misperceptions were assessed through a 12-item Likert scale included in a population health assessment mailed to households in the southwest United States. Linear regression models assessed the association between identifying as Hispanic/Latino and summed misperception score. RESULTS Among the 407 individuals in the analytic sample, 111 (27.3%) were Hispanic/Latino and 296 (72.7%) were non-Hispanic white. On average, Hispanics/Latinos had a 3.03-point higher HPV vaccine misperception sum score relative to non-Hispanic whites, indicating greater agreement with misperceptions (95% confidence interval: 1.16-4.88; p < 0.01). DISCUSSION Culturally relevant interventions are needed to address HPV vaccine misperceptions among Hispanics/Latinos as part of efforts toward HPV-associated cancer health equity.

Serum Phosphorus, Serum Bicarbonate, and Renal Function in Relation to Liver CYP1A2 Activity. Diagnostics (Basel) 2023; 13:2996. [PMID: 37761363 PMCID: PMC10529210 DOI: 10.3390/diagnostics13182996] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 09/11/2023] [Accepted: 09/13/2023] [Indexed: 09/29/2023] Open
Abstract
The liver plays an important role in normal metabolism and physiological functions such as acid-base balance; however, limited epidemiologic studies have investigated how the liver contributes toward acid-base balance using non-invasive biomarkers. We determined associations between serum biomarkers related to acid-base balance and renal function with liver CYP1A2 activity. We used data from 1381 participants of the 2009-2010 National Health and Nutrition Examination Survey (NHANES) with measurements of serum phosphorus, serum bicarbonate, caffeine intake, caffeine metabolites, and estimated glomerular filtration rate (eGFR). Liver CYP1A2 activity was estimated using urine caffeine metabolite indices, which were calculated as the ratio of one of the urine caffeine metabolites (i.e., paraxanthine and 1-methyluric acid) to caffeine intake. We analyzed associations in the whole data set and in different strata of hepatic steatosis index (HSI) based on different cut-points. We found that serum bicarbonate was positively associated with CYP1A2 activity in the whole data set when comparing persons with bicarbonate at Q4 to Q1 (β = 0.18, p = 0.10 for paraxanthine; β = 0.20, p = 0.02 for 1-methyluric acid). Furthermore, serum phosphorus was positively associated with CYP1A2 activity only in the stratum of 30 ≤ HSI < 36. Lastly, low eGFR was significantly associated with lower CYP1A2 activity measured with paraxanthine in the whole dataset and in all the strata with HSI < 42; when comparing eGFR < 60 to eGFR > 90, β estimates ranged from -0.41 to -1.38, p-values ranged from 0.0018 to 0.004. We observed an opposite trend in the highest stratum (HSI ≥ 42). Non-invasive measurements of serum bicarbonate, serum phosphorus, and eGFR have dynamic associations with CYP1A2 activity. These associations depend on the extent of liver damage and the caffeine metabolite used to assess CYP1A2 activity.

Living Alone, Physical Health, and Mortality in Breast Cancer Survivors: A Prospective Observational Cohort Study. Healthcare (Basel) 2023; 11:2379. [PMID: 37685413 PMCID: PMC10486593 DOI: 10.3390/healthcare11172379] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 08/16/2023] [Accepted: 08/17/2023] [Indexed: 09/10/2023] Open
Abstract
Living alone, particularly for individuals with poor physical health, can increase the likelihood of mortality. This study aimed to explore the individual and joint associations of living alone and physical health with overall mortality among breast cancer survivors in the Women's Healthy Eating and Living (WHEL). We collected baseline, 12-month and 48-month data among 2869 women enrolled in the WHEL cohort. Living alone was assessed as a binary variable (Yes, No), while scores of physical health were measured using the RAND Short Form-36 survey (SF-36), which include four domains (physical function, role limitation, bodily pain, and general health perceptions) and an overall summary score of physical health. Cox proportional hazard models were used to evaluate associations. No significant association between living alone and mortality was observed. However, several physical health measures showed significant associations with mortality (p-values < 0.05). For physical function, the multivariable model showed a hazard ratio (HR) of 2.1 (95% CI = 1.02-4.23). Furthermore, the study examined the joint impact of living alone and physical health measures on overall mortality. Among women with better physical function, those living alone had a 3.6-fold higher risk of death (95% CI = 1.01-12.89) compared to those not living alone. Similar trends were observed for pain. However, regarding role limitation, the pattern differed. Breast cancer survivors living alone with worse role limitations had the highest mortality compared to those not living alone but with better role limitations (HR = 2.6, 95% CI = 1.11-5.95). Similar trends were observed for general health perceptions. Our findings highlight that living alone amplifies the risk of mortality among breast cancer survivors within specific health groups.

The Independent and Joint Associations of Whole Grain and Refined Grain with Total Mortality among Breast Cancer Survivors: A Prospective Cohort Study. Nutrients 2022; 14:3333. [PMID: 36014839 PMCID: PMC9416636 DOI: 10.3390/nu14163333] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 08/08/2022] [Accepted: 08/12/2022] [Indexed: 07/30/2023] Open
Abstract
Breast cancer survivors often have a reduced digestive capacity to digest whole grains due to cancer treatment. The purpose of this study was to investigate the independent and joint associations of whole grain and refined grain consumption with total mortality among breast cancer survivors. We studied a cohort of 3081 female breast cancer survivors who provided demographic, dietary, and lifestyle data at baseline, year 1 and year 4. Mortality was assessed via semi-annual telephone interviews and confirmed by the National Death Index (NDI) and death certificates. We assessed the associations of whole grain and refined grain with incident of mortalities using Cox proportional hazards models. Increased whole grain consumption was marginally associated with an increased risk of total mortality (p = 0.07) but was not significantly associated with breast cancer-specific mortality (p = 0.55). An increased intake of refined grains was associated with an increased risk of both total (HR = 1.74; 95% CI,1.17 to 2.59) and breast cancer-specific mortality (HR = 1.16; 95% CI, 1.08 to 1.26). Furthermore, we examined the joint associations of whole grain and refined grain with total mortality. Among those with a high consumption of refined grain, those with high consumption of whole grain had a higher risk of total mortality (HR = 1.52, 95% CI, 1.07 to 2.14) than those with a low consumption of whole grain. Increased consumption of whole grains may exacerbate the adverse associations of refined grain with mortality among breast cancer survivors. Our findings indicate the need to revisit current dietary guidelines for breast cancer survivors regarding whole grain intake.

Cross-Sectional Study of Sexual Behavior, Alcohol Use, and Mental Health Conditions Associated With Sexually Transmitted Infections Among Deploying Shipboard US Military Personnel. Mil Med 2020; 184:e693-e700. [PMID: 31004170 DOI: 10.1093/milmed/usz070] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2018] [Revised: 01/30/2019] [Accepted: 03/13/2019] [Indexed: 11/12/2022] Open
Abstract
INTRODUCTION Limited comprehensive data exist on risk behavior associated with sexually transmitted infections (STI) among ship-assigned US military personnel during the predeployment time period (PDT). This study examined whether sexual risk behaviors, alcohol use, involuntary drug consumption (IDC), posttraumatic stress disorder (PTSD), and depression during the 12 months prior to deployment were associated with provider-diagnosed STIs in this population. MATERIALS AND METHODS Using cross-sectional data collected during 2012-2014 among sexually active personnel, multivariable regression assessed factors associated with STIs among all men (n = 1,831). Stratified analyses were conducted among men who have sex with women (MSW, n = 1,530), men who have sex with men or men and women (MSM, n = 83), and excluded those not reporting sexual partner gender (n = 218). RESULTS Among MSW, transactional sex (AOR 3.8, 95% CI 1.5-9.4) meeting sexual partners at work (AOR 4.3, 95% CI 2.0-9.2), IDC (AOR 6.6, 95% CI 3.0-14.5), and incomplete mental health assessments (AOR 4.4, 95% CI 1.6-12.0) were significantly associated with STIs after adjustment. Among all men, those who identified as MSM (AOR 4.6, 95% CI 1.9-11.2) and drug screen positive (AOR 3.3, 95% CI 1.3-8.6) were significantly more likely to report an STI. CONCLUSIONS Previously unreported factors significantly associated with STIs at the PDT among MSW in the adjusted analysis were meeting sexual partners at work and IDC. IDC during the PDT warrants further exploration. These results can inform tailored STI reduction interventions among shipboard personnel and similarly aged civilians undergoing similar transition/travel experiences.

Abstract
Background Sugar-sweetened beverage (SSB) consumption has been associated with cardiometabolic risk. However, the association between total and type of SSB intake and incident cardiovascular disease (CVD) end points such as myocardial infarction, stroke, and revascularization is limited. Methods and Results We examined the prospective association of baseline SSB consumption with incident CVD in 106 178 women free from CVD and diabetes mellitus in the CTS (California Teachers Study), a cohort of female teachers and administrators, followed since 1995. SSBs were defined as caloric soft drinks, sweetened bottled waters or teas, and fruit drinks, and derived from a self-administered food frequency questionnaire. CVD end points were based on annual linkage with statewide inpatient hospitalization records. Cox proportional hazards models were used to assess the association between SSB consumption and incident CVD. A total of 8848 CVD incident cases were documented over 20 years of follow-up. After adjusting for potential confounders, we observed higher hazard ratios (HRs) for CVD (HR, 1.19; 95% CI, 1.06-1.34), revascularization (HR, 1.26; 95% CI, 1.04-1.54]), and stroke (HR, 1.21; 95% CI, 1.04-1.41) in women who consumed ≥1 serving per day of SSBs compared with rare/never consumers. We also observed a higher risk of CVD in women who consumed ≥1 serving per day of fruit drinks (HR, 1.42; 95% CI, 1.00-2.01 [P trend=0.021]) and caloric soft drinks (HR, 1.23; 95% CI, 1.05-1.44 [P trend=0.0002]), compared with rare/never consumers. Conclusions Consuming ≥1 serving per day of SSB was associated with CVD, revascularization, and stroke. SSB intake might be a modifiable dietary target to reduce risk of CVD among women.

Abstract
BACKGROUND The association between sugar-sweetened beverage (SSB) consumption and colorectal cancer (CRC) risk remains unclear and published data are limited. METHODS The analytic cohort included 99,798 women, free of cancer at baseline, from the California Teachers Study, a longitudinal cohort comprised of 133,477 female teachers and administrators who were active or recently retired members of the California State Teachers Retirement System in 1995. SSB consumption constituted caloric soft drinks, sweetened bottled waters and teas, and fruit drinks, derived from a self-administered food frequency questionnaire. Consumption was divided into four categories: Rare or never, >rare/never to <1 serving/week, ≥1 serving/week to <1 serving/day, and ≥1 serving/day. CRC endpoints were based on annual linkage with California Cancer Registry, defined as first diagnosis of CRC, and classified following the Surveillance, Epidemiology, and End Results Program coding system. Multivariable-adjusted Cox proportional hazards models were used to generate hazard ratios (HR) and 95% confidence intervals (CI) for assessing the association between SSB consumption and incident CRC. RESULTS A total of 1,318 incident CRC cases were identified over 20 years of follow-up (54.5% proximal colon and 45.5% distal colorectum). Compared with rare/never consumers, the multivariable-adjusted HRs (95% CI) were 1.14 (0.86, 1.53) for total CRC; 1.11 (0.73, 1.68) for proximal colon; and 1.22 (0.80, 1.86) for distal colorectum cancers among women consuming ≥ 1 serving/day of SSBs. CONCLUSION SSBs were not significantly associated with CRC risk. The biological effects of high SSB consumption make it important to continue to evaluate whether SSBs are associated with CRC. Additionally, future studies should further assess SSBs in large, racial/ethnically diverse cohorts of males and females, and, if feasible, address changes in SSB consumption over time.

Associations between Dietary Acid Load and Biomarkers of Inflammation and Hyperglycemia in Breast Cancer Survivors. Nutrients 2019; 11:nu11081913. [PMID: 31443226 PMCID: PMC6723571 DOI: 10.3390/nu11081913] [Citation(s) in RCA: 31] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2019] [Revised: 07/31/2019] [Accepted: 08/09/2019] [Indexed: 12/12/2022] Open
Abstract
Metabolic acidosis can lead to inflammation, tissue damage, and cancer metastasis. Dietary acid load contributes to metabolic acidosis if endogenous acid-base balance is not properly regulated. Breast cancer survivors have reduced capacities to adjust their acid-base balance; yet, the associations between dietary acid load and inflammation and hyperglycemia have not been examined among them. We analyzed data collected from 3042 breast cancer survivors enrolled in the Women's Healthy Eating and Living (WHEL) Study who had provided detailed dietary intakes and measurements of plasma C-reactive protein (CRP) and hemoglobin A1c (HbA1c). Using a cross-sectional design, we found positive associations between dietary acid load and plasma CRP and HbA1c. In the multivariable-adjusted models, compared to women with the lowest quartile, the intakes of dietary acid load among women with the highest quartile showed 30-33% increases of CRP and 6-9% increases of HbA1c. Our study is the first to demonstrate positive associations between dietary acid load and CRP and HbA1c in breast cancer survivors. Our study identifies a novel dietary factor that may lead to inflammation and hyperglycemia, both of which are strong risk factors for breast cancer recurrence and comorbidities.

Unfair Treatment and Periodontitis Among Adults in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). J Racial Ethn Health Disparities 2018; 5:1093-1106. [PMID: 29327269 PMCID: PMC6760848 DOI: 10.1007/s40615-017-0459-5] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2017] [Revised: 12/01/2017] [Accepted: 12/28/2017] [Indexed: 10/18/2022]
Abstract
This study investigates how perceived unfair treatment, towards self and observed towards others due to ethnicity, is associated with periodontitis among diverse Hispanic/Latino adults, accounting for sociodemographic, health behavior, and acculturation factors. Baseline (2008-2011) dental and survey data from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), a multicenter epidemiologic study, were analyzed (N = 12,750). Crude and adjusted prevalence ratios and confidence limits were estimated. Half (49%) reported never being treated unfairly, while 41% reported they were sometimes, and 10% reported it often/always. One third (32%) never saw others treated unfairly, while 42% reported it sometimes, and 26% reported it often/always. In the final fully adjusted model, the prevalence of periodontitis was higher among adults who were as follows: non-Dominican, older, male, had a past year dental visit, current and former smokers, and among those who observed unfair treatment towards others. Lower prevalence was associated with higher income, higher educational attainment, less than full-time employment, reporting experiencing unfair treatment, higher acculturation scores, and having health insurance. Perceived unfair treatment towards self was negatively associated with periodontitis prevalence, while observed unfair treatment towards others was positively associated with the outcome among diverse Hispanics/Latinos. The associations between unfair treatment and periodontitis warrant further exploration.

Abstract
BACKGROUND Periodontal disease has been shown to be associated with cardiovascular disease (CVD). No known studies evaluate the relationship between periodontal disease status and biomarkers of CVD risk in the American Indian/Alaskan Native (AI/AN) population despite their disproportionately high rates of poor oral health and cardiovascular disease-related outcomes. This study compared levels of interleukin (IL)-6 and C-reactive protein (CRP) across increasing severity of periodontal disease status among younger adults between the ages of 21 and 43 years. METHODS Plasma levels of IL-6 and CRP were measured in adult participants (ages 21 to 43 years) as part of a study of periodontal disease and CVD risk among an AI/AN population in southern California (n = 59). Periodontal evaluations were performed and disease status was classified into three categories based on highest probing depth (none/mild: < 3 mm; moderate: 4 to 5 mm; severe: ≥6 mm). Participants with known systemic disease or active infection were excluded. RESULTS Severe periodontitis was significantly associated with increased levels of IL-6 compared with those with none or mild periodontitis before controlling for other variables (P = 0.02), but lacked significance after controlling for sex, BMI, smoking status, and high-density lipoprotein (P = 0.09). Moderate periodontal disease was positively associated with IL-6 levels after controlling for potential confounders (P = 0.01). Periodontal status was not associated with CRP, before or after adjusting for covariates. CONCLUSIONS In this otherwise healthy AI/AN adult sample, moderate periodontal disease compared with none or mild periodontal disease was associated with increased levels of IL-6. High levels of CRP found in this population warrant further research.

Abstract
This study examines the demographic representativeness of the County of San Diego Body Mass Index (BMI) Surveillance System to determine if the BMI estimates being obtained from this convenience sample of individuals who visited their healthcare provider for outpatient services can be generalized to the general population of San Diego. Height and weight were transmitted from electronic health records systems to the San Diego Immunization Registry (SDIR). Age, gender, and race/ethnicity of this sample are compared to general population estimates by sub-regional area (SRA) (n = 41) to account for regional demographic differences. A < 10% difference (calculated as the ratio of the differences between the frequencies of a sub-group in this sample and general population estimates obtained from the U.S. Census Bureau) was used to determine representativeness. In 2011, the sample consisted of 352,924 residents aged 2-100 years. The younger age groups (2-11, 12-17 years) and the oldest age group (≥65 years) were representative in 90, 75, and 85% of SRAs, respectively. Furthermore, at least one of the five racial/ethnic groups was represented in 71% of SRAs. This BMI Surveillance System was found to demographically represent some SRAs well, suggesting that this registry-based surveillance system may be useful in estimating and monitoring neighborhood-level BMI data.

Abstract
RATIONALE Accurate reference values for spirometry are important because the results are used for diagnosing common chronic lung diseases such as asthma and chronic obstructive pulmonary disease, estimating physiologic impairment, and predicting all-cause mortality. Reference equations have been established for Mexican Americans but not for others with Hispanic/Latino backgrounds. OBJECTIVES To develop spirometry reference equations for adult Hispanic/Latino background groups in the United States. METHODS The HCHS/SOL (Hispanic Community Health Study/Study of Latinos) recruited a population-based probability sample of 16,415 Hispanics/Latinos aged 18-74 years living in the Bronx, Chicago, Miami, and San Diego. Participants self-identified as being of Puerto Rican, Cuban, Dominican, Mexican, or Central or South American background. Spirometry was performed using standardized methods with central quality control monitoring. Spirometric measures from a subset of 6,425 never-smoking participants without respiratory symptoms or disease were modeled as a function of sex, age, height, and Hispanic/Latino background to produce background-specific reference equations for the predicted value and lower limit of normal. MEASUREMENTS AND MAIN RESULTS Dominican and Puerto Rican Americans had substantially lower predicted and lower limit of normal values for FVC and FEV1 than those in other Hispanic/Latino background groups and also than Mexican American values from NHANES III (Third National Health and Nutrition Examination Survey). CONCLUSIONS For patients of Dominican and Puerto Rican background who present with pulmonary symptoms in clinical practice, use of background-specific spirometry reference equations may provide more appropriate predicted and lower limit of normal values, enabling more accurate diagnoses of abnormality and physiologic impairment.

Abstract
Undocumented immigration often presents with multiple stressors and contextual challenges, which may diminish mental health. This study is the first to provide population-based estimates for the prevalence of traumatic events and its association to clinically significant psychological distress among undocumented Mexican immigrants in the United States. This cross-sectional study used respondent-driven sampling to obtain and analyze data from clinical interviews with 248 undocumented Mexican immigrants residing in high-risk neighborhoods near the California-Mexico border. Overall, 82.7% of participants reported a history of traumatic events, with 47.0% of these meeting the criteria for clinically significant psychological distress. After controlling for relevant covariates, having experienced material deprivation, odds ratio (OR) = 2.26, 95% CI [1.18, 4.31], p = .013, and bodily injury, OR = 2.96, 95% CI [1.50, 5.83], p = .002, and not having a history of deportation, OR = 0.36, 95% CI [0.17, 0.79], p = .011, were associated with clinically significant psychological distress. These results support the need to revisit health and immigration policies and to devise solutions grounded in empirical evidence aimed at preventing the negative effects of trauma and psychological distress in this population.

Abstract
Background Posttraumatic growth is the positive change resulting from traumatic experiences and is typically assessed with retrospective measures like the Posttraumatic Growth Inventory (PTGI). The PTGI was designed to include reference to a specific traumatic event, making it difficult to implement, without change, in prospective survey studies. Thus, a modified Posttraumatic Growth Inventory–Short Form (PTGI-SF) was included in a large prospective study of current and former U.S. military personnel. The current study provides preliminary psychometric data for this modified measure and its ability to assess psychological well-being at a single time point. Methods The study population (N = 135,843) was randomly and equally split into exploratory and confirmatory samples that were proportionately balanced on trauma criterion. Exploratory factor analysis and confirmatory factor analysis (CFA) were performed to assess the psychometric validity of the modified measure. The final model was also assessed in a subset of the confirmatory sample with a history of trauma using CFA. Results Results supported a single-factor model with two additional correlations between items assessing spirituality and items assessing compassion/appreciation for others. This model also fits among the subset with a history of trauma. The resulting measure was strongly associated with social support and personal mastery. Conclusions The modified PTGI-SF in this study captures psychological well-being in cross-sectional assessments, in addition to being able to measure posttraumatic growth with multiple assessments. Results indicate that the modified measure is represented by a single factor, but that items assessing spirituality and compassion/appreciation for others may be used alone to better capture these constructs.

Abstract
BACKGROUND Analyzing telemetry electrocardiogram (ECG) data over an extended period is often time-consuming because digital records are not widely available at hospitals. Investigating trends and patterns in the ECG data could lead to establishing predictors that would shorten response time to in-hospital cardiac arrest (I-HCA). This study was conducted to validate a novel method of digitizing paper ECG tracings from telemetry systems in order to facilitate the use of heart rate as a diagnostic feature prior to I-HCA. METHODS This multicenter study used telemetry to investigate full-disclosure ECG papers of 44 cardiovascular patients obtained within 1 hr of I-HCA with initial rhythms of pulseless electrical activity and asystole. Digital ECGs were available for seven of these patients. An algorithm to digitize the full-disclosure ECG papers was developed using the shortest path method. The heart rate was measured manually (averaging R-R intervals) for ECG papers and automatically for digitized and digital ECGs. RESULTS Significant correlations were found between manual and automated measurements of digitized ECGs (p < .001) and between digitized and digital ECGs (p < .001). Bland-Altman methods showed bias = .001 s, SD = .0276 s, lower and upper 95% limits of agreement for digitized and digital ECGs = .055 and -.053 s, and percentage error = 0.22%. Root mean square (rms), percentage rms difference, and signal to noise ratio values were in acceptable ranges. CONCLUSION The digitization method was validated. Digitized ECG provides an efficient and accurate way of measuring heart rate over an extended period of time.

Abstract
OBJECTIVE To determine the effect of rheumatoid arthritis (RA) disease severity on pregnancy outcomes in pregnant women with and without autoimmune diseases. METHODS A prospective cohort study was conducted using the Organization of Teratology Information Specialists Autoimmune Diseases in Pregnancy Project. Pregnant women with RA enrolled between 2005 and 2013 were selected if they (1) delivered a live-born singleton infant; and (2) completed 3 telephone-based measures of RA disease severity prior to 20 weeks' gestation, including the Health Assessment Questionnaire Disability Index (HAQ-DI), pain score, and patient's global scale. Associations between RA disease severity and preterm delivery, small for gestational age (SGA), or cesarean delivery were tested in unadjusted and multivariate analyses using modified Poisson regression models. RESULTS The sample consisted of 440 women with RA. Several unadjusted comparisons yielded significant associations. After adjustment for covariates, increasing disease severity was associated with risk for preterm delivery and SGA. For each unit increase in HAQ-DI (0-1), the adjusted relative risk (aRR) for preterm delivery increased by 58% (aRR 1.58, 95% CI 1.17-2.15). Among those with HAQ-DI > 0.5, the aRR for SGA was 1.81 (95% CI 1.01-3.33). CONCLUSION RA disease severity in early pregnancy, as measured in this study, was predictive of preterm delivery and SGA. These findings suggest that the risk of preterm delivery and SGA in women with RA might be lowered if RA is well controlled early in pregnancy.

Abstract
Introduction Although Latinos have lower hypertension rates than non-Latino whites and African Americans, they have a higher prevalence of undiagnosed and uncontrolled hypertension. Research on predictors of hypertension has mostly focused on intrapersonal factors with no studies assessing the combined influence of intrapersonal, interpersonal, and environmental factors. The purpose of this study was to assess a broad range of correlates including intrapersonal, interpersonal, and environmental factors on measured blood pressure category (nonhypertensive, prehypertensive, and hypertensive) in a sample of Latina women residing in San Diego, California. Methods This cross-sectional study used baseline data from the San Diego Prevention Research Center’s Familias Sanas y Activas program, a promotora-led physical activity intervention. The sample was 331 Latinas who self-selected into this program. Backward conditional logistic regression analysis was conducted to determine the strongest correlates of measured blood pressure category. Results Logistic regression analysis suggested that the strongest correlates of prehypertension were soda consumption (odds ratio [OR] = 1.34, [1.00–1.80], P ≤ .05) and age (OR = 1.03, [1.00–1.05], P ≤ .05). The strongest correlates of hypertension were soda consumption (OR = 1.92, [1.20–3.07], P ≤ .01), age (OR = 1.09, [1.05–1.13], P ≤ .001), and measured body mass index (OR = 1.13, [1.05–1.22], P ≤ .001). All analyses controlled for age and education. No interpersonal or environmental correlates were significantly associated with blood pressure category. Conclusion Future research should aim to further understand the role of soda consumption on risk for hypertension in this population. Furthermore, interventions aimed at preventing hypertension may want to focus on intrapersonal level factors.

Abstract
The objective of this study was to investigate the association of parent acculturation with child fruit and vegetable consumption and obesity, as measured by body mass index (BMI). Participants included 250 Mexican-American and other Hispanic families living within San Diego County. Height and weight measurements were collected to calculate the age- and sex-specific BMI for each child and parent, and parents completed self-administered surveys. Child BMI z-score was significantly related to parent BMI after controlling for parent acculturation and parent birth place (β = 0.05, p < 0.01). Child fruit consumption was significantly associated with parent acculturation (β = -0.02, p = 0.01) and parent BMI (β = 0.02, p = 0.04) after adjusting for the other variables in the model. Child vegetable consumption was not significantly related to parent acculturation. Findings suggest that parental weight status may be more predictive of child obesity than acculturation, and highlight the need to examine culturally relevant behavioral and psychosocial factors related to childhood obesity and dietary behaviors.

Abstract
AIMS To identify factors associated with time to initiation of (i) sex work prior to injecting drugs initiation; (ii) injection drug use prior to sex work initiation; and (iii) concurrent sex work and injection drug use (i.e. initiated at the same age) among female sex workers who currently inject drugs (FSW-IDU). DESIGN Parametric survival analysis of baseline data for time to initiation event. SETTING Tijuana and Ciudad Juarez situated on the Mexico-US border. PARTICIPANTS A total of 557 FSW-IDUs aged ≥18 years. MEASUREMENTS Interview-administered surveys assessing context of sex work and injection drug use initiation. FINDINGS Nearly half (n = 258) initiated sex work prior to beginning to inject, a third (n = 163) initiated injection first and a quarter (n = 136) initiated both sex work and injection drug use concurrently. Low education and living in Ciudad Juarez accelerated time to sex work initiation. Being from a southern Mexican state and initiating drug use with inhalants delayed the time to first injection drug use. Having an intimate partner encourage entry into sex work and first injecting drugs to deal with depression accelerated time to initiating sex work and injection concurrently. Early physical abuse accelerated time to initiating sex work and injection, and substantially accelerated time to initiation of both behaviors concurrently. CONCLUSIONS Among female sex workers who currently inject drugs in two Mexican-US border cities, nearly half appear to initiate sex work prior to beginning to inject, nearly one-third initiate injection drug use before beginning sex work and one-quarter initiate both behaviors concurrently. Predictors of these three trajectories differ, and this provides possible modifiable targets for prevention.

Abstract
Smoking, drinking, and illicit drug use are leading causes of morbidity and mortality, both during adolescence as well as later in life. Although for some adolescents, substance use may last for only a brief period of experimentation, use of these substances in adolescence may have negative consequences. The determination of how well national and local policy and intervention efforts address teen substance use depends largely on the collection of valid and accurate data. Assessments of substance use rely heavily on retrospective self-report measures. The reliability and validity of self-reported substance use measures, however, may be limited by various sources of measurement error. This study utilizes four waves of data from the National Longitudinal Survey of Youth spanning eight years. Our wave-to-wave analyses examined the accuracy of self-reported age of onset for cigarette, alcohol and marijuana users. Findings indicate that approximately one-fourth of cigarette users, one-fifth of alcohol users and one-third of marijuana users reported their age of onset exactly the same across waves. Of those who reported the age of onset inaccurately, the error tended to be in the direction of reporting their age of onset as older at a latter wave relative to what was reported previously, known as forward telescoping. Results from multiple linear regression analyses showed that the single most consistent variable associated with telescoping was the number of years since the substance was first reported. Time since first report was the single consistent and strongly associated with telescoping in each wave-to-wave comparison for all three substances under study. Implications for policy and research are discussed.

Abstract
Background Rapid influenza diagnosis is important for early identification of outbreaks, effective management of high-risk contacts, appropriate antiviral use, decreased inappropriate antibiotic use and avoidance of unnecessary laboratory testing. Given the inconsistent performance of many rapid influenza tests, clinical diagnosis remains integral for optimizing influenza management. However, reliable clinical diagnostic methods are not well-established. This study assesses predictors of influenza, and its various subtypes, in a broad population at the point of care, across age groups, then evaluates the performance of clinical case definitions composed of identified predictors. Methods Respiratory specimens and demographic and clinical data were obtained from 3- to 80-year-old US military family members presenting for care with influenza-like illness (ILI) from November 2007 to April 2008. Molecular and virus isolation techniques were used to detect and subtype influenza viruses. Associations between influenza diagnosis and demographic/clinical parameters were assessed by logistic regression, including influenza type and subtype analyses. The predictive values of multiple combinations of identified clinical predictors (case definitions), and the Centers for Disease Control and Prevention (CDC) ILI case definition, were estimated. Results Of 789 subjects, 220 (28%) had laboratory-confirmed influenza (51 A(H1), 46 A(H3), 19 A(unsubtypeable), 67 B, 1 AB coinfection), with the proportion of influenza A to B cases highest among 6- to 17-year-olds (p = 0.019). Independent predictors of influenza included fever, cough, acute onset, body aches, and vaccination status among 6- to 49-year-olds, only vaccination among 3- to 5-year-olds, and only fever among 50- to 80-year-olds. Among 6- to 49-year-olds, some clinical case definitions were highly sensitive (100.0%) or specific (98.6%), but none had both parameters over 60%, though many performed better than the CDC ILI case definition (sensitivity 37.7%, 95% confidence interval 33.6–41.9% in total study population). Conclusions Patterns of influenza predictors differed across age groups, with most predictors identified among 6- to 49-year-olds. No combination of clinical and demographic predictors served as a reliable diagnostic case definition in the population and influenza season studied. A standardized clinical case definition combined with a point-of-care laboratory test may be the optimal rapid diagnostic strategy available.

Abstract
The objective of this study was to explore the relationship between severity of depression and cardiovascular disease (CVD) risk factors among selected Latino patients within a primary care setting. We conducted a cross-sectional analysis of 164 low-income Latino patients at San Ysidro Health Center (SYHC) who had been recruited into a mental health program between January 2007 and March 2008. Patients were between the ages of 18 and 83 years, 54 were males and 109 females. Patients were screened using the 9-item patient health questionnaire (PHQ-9), a standardized instrument used to measure depression severity. We used regression models to analyze the relationship between severity of depression and CVD risk factors. Seventy-eight percent of the patients had at least mild depression based on PHQ-9 score categories. Significant age-adjusted pairwise associations were found with CVD risk factors; body mass index (BMI), diabetes status, serum cholesterol level, and serum triglyceride level were all associated with depression severity score. Regression models indicated that diabetic patients on anti-depressive medication with higher BMI scores and triglyceride levels had significantly higher depression severity scores. Clinicians should be made aware that depressive symptoms may impede efforts to modify BMI, serum triglycerides, anti-depression medication, and diabetes among Latino patients. They should, therefore, screen and treat depression among Latinos at risk to CVD.

Abstract
INTRODUCTION Tobacco use is of particular concern to the U.S. Department of Defense because the military historically has had higher and heavier rates of tobacco use than civilians. Few prospective studies have examined the association of cigarette smoking with medical outcomes, particularly among initially healthy female military personnel. METHODS This prospective cohort study followed over 5,000 young U.S. Navy female recruits varying in their smoking status at entry into the Navy and collected their subsequent hospitalization data (i.e., International Classification of Diseases, Ninth Revision codes) for up to 7-8 years of service. RESULTS Results indicated that after adjusting for differences in time at risk and sociodemographic variables, daily smokers (compared with never-and other smokers) had higher rates of hospitalization for any reason and for musculoskeletal conditions. Daily smokers also had higher rates than never- and other smokers for non-pregnancy-related hospitalizations and for mental disorders, although only the daily/other differences reached statistical significance. Daily smokers' average number of days hospitalized was significantly longer than that of never- and other smokers. DISCUSSION Results suggest that young women do not have to wait decades to experience the harmful effects of smoking. A recent history of cigarette smoking is an important determinant of hospitalization risk for even young healthy women in the U.S. Navy.
