Estimating causal and time-varying effects of maternal smoking on youth smoking. Addict Behav 2021; 120:106982. [PMID: 34022755 PMCID: PMC8194413 DOI: 10.1016/j.addbeh.2021.106982] [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: 12/07/2020] [Revised: 04/29/2021] [Accepted: 05/03/2021] [Indexed: 11/26/2022]
Abstract
INTRODUCTION Maternal smoking is a well-known risk factor for youth smoking, yet whether this relationship is causal remains unresolved. This study utilizes propensity score methods for causal inference to robustly account for shared risk factors between maternal and offspring smoking. METHODS An 8-year longitudinal cohort of 900 adolescents in the Chicago area were followed starting from approximately age 15.6. The effects of maternal lifetime smoking (MLS) and prenatal tobacco exposure (PTE) (among participants reporting MLS) on offspring's past 30-day smoking, daily smoking status and smoking frequency were examined using logistic regression and Poisson regression after nearest-neighbor propensity matching. Age dependency of this relationship was then examined across the age range of 15-25 using time-varying effect modeling. RESULTS Propensity matching yielded 438 and 132 pairs for MLS and PTE study samples, respectively. MLS demonstrated significant associations with past 30-day smoking (RR 1.09; 95% CI 1.04-1.14), daily smoking (RR 1.08; 95% CI 1.05-1.12), and smoking frequency of offspring (RR 1.32; 95% CI 1.15-1.52), with stable effects across age. Among participants reporting MLS, having PTE showed significant additional effects on daily smoking (RR 1.09; 95% CI 1.02-1.17) and age-dependency that showed significance during young adulthood but not adolescence. CONCLUSION The relationship between maternal and offspring smoking was not fully accounted for by shared risk factors, suggesting possible causation with PTE having a delayed effect across age. Targeted prevention efforts should be made on maternal smoking-exposed adolescents to mitigate their risks of developing heavy smoking habits in adulthood.

The effect of maternal smoking on offspring smoking is unrelated to heritable personality traits or initial subjective experiences. Nicotine Tob Res 2021; 23:1754-1762. [PMID: 33912956 DOI: 10.1093/ntr/ntab081] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2020] [Accepted: 04/23/2021] [Indexed: 02/06/2023]
Abstract
INTRODUCTION Maternal smoking is a risk factor for offspring smoking. Lifetime maternal smoking vs. prenatal tobacco exposure (PTE) appear to act through different mechanisms. This study tested the hypothesis that maternal smoking measures' effects on offspring smoking could be attributable to hereditary mechanisms: personality traits (novelty-seeking, impulsivity, neuroticism, self-esteem) and initial subjective smoking experiences (pleasurable, unpleasurable, dizziness). METHODS Data were drawn from the Social and Emotional Contexts of Adolescent Smoking Patterns (SECASP) study, an 8-year longitudinal study of 9 th or 10 th graders at baseline (≈age 15) who experiment with smoking (<100 lifetime cigarettes; N=594) at baseline. Young adult smoking frequency at the 8-year follow-up (≈age 23) was examined as a function of baseline characteristics (heritable trait, maternal smoking, PTE, sex) and baseline smoking frequency and nicotine dependence. Structural equation models determined whether inclusion of each heritable trait among offspring confounded the effects of maternal smoking (PTE or maternal smoking) on offspring smoking and nicotine dependence. RESULTS Impulsiveness was associated with intermediate adolescent smoking frequency (B=0.135, SD=0.043 p=0.002) and nicotine dependence (B=0.012, SD=0.003, p<0.001). Unpleasurable first experience (B=0.886, SD=0.374, p=0.018) and dizziness (B=0.629, SD=0.293, p=0.032) showed a trend with intermediate smoking frequency that was non-significant after correcting for multiple comparisons. These traits did not confound maternal smoking's effects. CONCLUSIONS None of the heritable traits examined in this model explained the effect of maternal smoking measures on adolescence or young adulthood offspring smoking. Further research is needed to elucidate the mechanism by which PTE and maternal smoking are linked to offspring smoking.

The Role of Nicotine Dependence in E-Cigarettes' Potential for Smoking Reduction. Nicotine Tob Res 2019; 20:1272-1277.

Abstract
Introduction E-cigarettes (Electronic Nicotine Delivery Systems, or ENDS) are an increasingly popular tobacco product among youth. Some evidence suggests that e-cigarettes may be effective for harm reduction and smoking cessation, although these claims remain controversial. Little is known about how nicotine dependence may contribute to e-cigarettes' effectiveness in reducing or quitting conventional smoking. Methods A cohort of young adults were surveyed over 4 years (approximately ages 19-23). Varying-coefficient models (VCMs) were used to examine the relationship between e-cigarette use and conventional smoking frequency, and how this relationship varies across users with different nicotine dependence levels. Results Lifetime, but not recent, e-cigarette use was associated with less frequent concurrent smoking of conventional cigarettes among those with high levels of nicotine dependence. However, nondependent e-cigarette users smoked conventional cigarettes slightly more frequently than those who had never used e-cigarettes. Nearly half of ever e-cigarette users reported using them to quit smoking at the last measurement wave. For those who used e-cigarettes in a cessation attempt, the frequency of e-cigarette use was not associated with reductions in future conventional smoking frequency. Conclusions These findings offer possible support that e-cigarettes may act as a smoking reduction method among highly nicotine-dependent young adult cigarette smokers. However, the opposite was found in non-dependent smokers, suggesting that e-cigarette use should be discouraged among novice tobacco users. Additionally, although a substantial proportion of young adults used e-cigarettes to help them quit smoking, these self-initiated quit attempts with e-cigarettes were not associated with future smoking reduction or cessation. Implications This study offers potential support for e-cigarettes as a smoking reduction tool among highly nicotine-dependent young adult conventional smokers, although the extent and nature of this remains unclear. The use of e-cigarettes as a quit aid was not associated with reductions in conventional smoking, consistent with most other quit aids in this sample except for nicotine replacement therapy, which was only effective for the most dependent smokers. Notably, these findings highlight the necessity of accounting for smokers' nicotine dependence levels when examining tobacco use patterns.

Abstract
Little research has evaluated whether conflicting evidence for gender and racial/ethnic differences in nicotine dependence (ND) may be attributed to differences in psychometric properties of ND symptoms, particularly for young Hispanic smokers. Inadequate racial/ethnic diversity and limited smoking exposure variability has hampered research in young smokers. We used integrative data analysis (IDA) to pool DSM-IV ND symptom data for current smokers aged 12-25 (N = 20,328) from three nationally representative surveys (1999, 2000 National Surveys on Drug Use and Health (NSDUH) and Wave 1 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Moderated nonlinear factor analysis (MNLFA) tested symptom measurement invariance in the pooled sample containing greater ethnic and smoking exposure variability. There was study noninvariance for most symptoms. NESARC participants were more likely to report tolerance, using larger amounts or for longer periods, inability to cut down/quit, and more time spent smoking at higher levels of ND severity, but reported emotional/physical health problems at lower ND severity. Four symptoms showed gender or race/ethnicity noninvariance, but observed differences were small. An ND severity factor score adjusting for symptom noninvariance related to study membership, gender, and race/ethnicity did not differ substantively from traditional DSM-IV diagnosis and number of endorsed symptoms in estimated gender and race/ethnicity differences in ND. Results were consistent with studies finding minimal gender and racial/ethnic differences in ND, and suggest that symptom noninvariance is not a major contributor to observed differences. Results support IDA as a potentially promising approach for testing novel ND hypotheses not possible in independent studies.

The role of nicotinic receptor genes (CHRN) in the pathways of prenatal tobacco exposure on smoking behavior among young adult light smokers. Addict Behav 2018; 84:231-237. [PMID: 29751336 DOI: 10.1016/j.addbeh.2018.05.001] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2018] [Revised: 04/27/2018] [Accepted: 05/01/2018] [Indexed: 10/17/2022]
Abstract
BACKGROUND Prenatal tobacco exposure (PTE) is associated with more frequent smoking among young, light smokers. Little is known about how nicotinic acetylcholine receptor (CHRN) genes may contribute to this relationship. METHODS Data were drawn from a longitudinal cohort of young light smokers of European ancestry (N = 511). Three single nucleotide polymorphisms (SNPs) among offspring, rs16969968 and rs6495308 in CHRNA5A3B4 and rs2304297 in CHRNB3A6, were analyzed with respect to whether they 1) predict PTE status; 2) confound the previously-reported effects of PTE on future smoking; 3) have effects on youth smoking frequency that are mediated through PTE; and 4) have effects that are moderated by PTE. RESULTS rs2304297 and rs6495308 were associated with increased likelihood and severity of PTE, respectively. In a path analysis, rs16969968 directly predicted more frequent smoking in young adulthood (B = 1.50, p = .044); this association was independent of, and not mediated by, PTE. The risk of rs16969968 (IRR = 1.07, p = .015) and the protective effect of rs2304297 (IRR = 0.84, p < .001) on smoking frequency were not moderated by PTE. PTE moderated the effect of rs6495308, such that these alleles were protective against later smoking frequency only among non-exposed youth (IRR = 0.85, p < .001). CONCLUSIONS The association between offspring CHRNB3A6 and PTE is a novel finding. The risk of rs16969968 on youth smoking is independent and unrelated to that of PTE among young, light smokers. PTE moderates the protective effect of rs6495308 on youth smoking frequency. However, PTE's pathway to youth smoking behavior was not explained by these genetic factors, leaving its mechanism(s) of action unclear.

Abstract
BACKGROUND Sexually transmitted diseases (STDs) are increasing among gay, bisexual, and other men who have sex with men (MSM). Little is known about the use of websites and mobile phone applications to meet sexual partners ("hookup sites") and association with STD diagnoses. METHODS We performed a demographic and behavioral assessment of 415 MSM presenting to the Rhode Island STD clinic. Bivariate and multivariable analyses assessed associations between using hookup sites and testing positive for syphilis, gonorrhea, or chlamydia. Venue-based affiliation networks were created to evaluate hookup sites and their association with STD diagnoses. RESULTS Among 415 MSM, 78% reported meeting a partner online in the last 12 months, and 25% tested positive for at least one STD. Men who met partners online were more likely to be white (67% vs. 54%, P = 0.03) and have more than 10 lifetime partners (87% vs. 58%, P < 0.05). The most commonly used hookup sites included Grindr (78%), Scruff (35%), and Tinder (22%). In the multivariable analysis, only Scruff use was associated with testing positive for an STD (odds ratio, 2.28; 95% confidence interval, 1.09-4.94). However, among men who met partners online, 75% of men diagnosed as having an STD had met a sexual partner on Grindr, including 100% of those who were diagnosed as having gonorrhea. CONCLUSIONS Use of hookup sites was nearly ubiquitous among MSM undergoing STD screening. Specific hookup sites were significantly associated with STD diagnoses among MSM. Greater efforts are needed to promote STD screening and prevention among MSM who meet partners online.

Evaluating the mutual pathways among electronic cigarette use, conventional smoking and nicotine dependence. Addiction 2018; 113:325-333.

Abstract
BACKGROUND AND AIMS The implications of the rapid rise in electronic cigarette (e-cigarette) use remain unknown. We examined mutual associations between e-cigarette use, conventional cigarette use and nicotine dependence over time to (1) test the association between e-cigarette use and later conventional smoking (both direct and via nicotine dependence), (2) test the converse associations and (3) determine the strongest pathways predicting each product's use. DESIGN Data from four annual waves of a prospective cohort study were analyzed. Path analysis modeled the bidirectional, longitudinal relationships between past-month smoking frequency, past-month e-cigarette frequency and nicotine dependence. SETTING Chicago area, Illinois, USA. PARTICIPANTS A total of 1007 young adult smokers and non-smokers (ages 19-23 years). MEASUREMENTS Frequency of (1) cigarettes and (2) e-cigarettes was the number of days in the past 30 on which the product was used. The Nicotine Dependence Syndrome Scale measured nicotine dependence to cigarettes. FINDINGS E-cigarette use was not associated significantly with later conventional smoking, either directly (β = 0.021, P = 0.081) or through nicotine dependence (β = 0.005, P = 0.693). Conventional smoking was associated positively with later e-cigarette use, both directly (β = 0.118, P < 0.001) and through nicotine dependence (β = 0.139, P < 0.001). The strongest predictors of each product's use was prior use of the same product; this pathway was strong for conventional cigarettes (β = 0.604, P < 0.001) but weak for e-cigarettes (β = 0.120, P < 0.001). Nicotine dependence moderately strongly predicted later conventional smoking (β = 0.169, P < 0.001), but was a weak predictor of later e-cigarette use (β = 0.069, P = 0.039). CONCLUSIONS Nicotine dependence is not a significant mechanism for e-cigarettes' purported effect on heavier future conventional smoking among young adults. Nicotine dependence may be a mechanism for increases in e-cigarette use among heavier conventional smokers, consistent with e-cigarettes as a smoking reduction tool. Overall, conventional smoking and, to a lesser extent, its resulting nicotine dependence, are the strongest drivers or signals of later cigarette and e-cigarette use.

Abstract
Novice and light adolescent smokers can develop symptoms of nicotine dependence, which predicts smoking behavior several years into the future. However, little is known about how the association between these early - emerging symptoms and later smoker behaviors may change across time from early adolescence into young adulthood. Data were drawn from a 7-year longitudinal study of experimental (<100 cigarettes/lifetime; N = 594) and light (100+ cigarettes/lifetime, but ≤5 cigarettes/day; N = 152) adolescent smokers. Time-varying effect models were used to examine the relationship between baseline nicotine dependence (assessed at age 15 ± 2 years) and future smoking frequency through age 24, after controlling for concurrent smoking heaviness. Baseline smoking status, race, and sex were examined as potential moderators of this relationship. Nicotine dependence symptoms assessed at approximately age 15 significantly predicted smoking frequency through age 24, over and above concurrent smoking heaviness, though it showed declining trends at older ages. Predictive validity was weaker among experimenters at young ages (<16), but stronger at older ages (20-23), relative to light smokers. Additionally, nicotine dependence was a stronger predictor of smoking frequency for white smokers around baseline (ages 14.5-16), relative to nonwhite smokers. Nicotine dependence assessed in mid-adolescence predicts smoking frequency well into early adulthood, over and above concurrent smoking heaviness, especially among novice smokers and nonwhite smokers. Early-emerging nicotine dependence is a promising marker for screening and interventions aimed at preventing smoking progression.

Abstract
This article presents a model developed and assessed by a women's health research team to enhance sensitivity and increase readability of a survey to be used with community-based women. The survey consisted of quantitative measures of AIDS-related attitudes and behaviors, developed and used with traditional-aged college populations, and included questions of a highly personal nature. In Study 1, 30 women with English reading levels of third grade and above from two targeted community populations completed a survey in two waves of focus groups and gave feedback about readability, length, format, content, emotional responses, truthfulness in responding, and opinions about the research. Problem areas and changes that made the survey more readable, understandable, emotionally sensitive, and effective are reviewed. In Study 2, pre- and postmodification versions of nine scales are compared in 430 traditionalaged college women (pre) and 793 community-based women (post), the latter broken into subsamples for more refined comparisons. Results of five psychometric analyses demonstrate that psychometric integrity does not have to be hurt by such changes. In addition, this process illustrates how researchers can gain a better understanding of participants and their reactions to the research process through qualitative research methods.

Abstract
INTRODUCTION Over the past decade, there has been a sharp increase in the number of newly identified synthetic drugs. These new drugs are often derivatives of previously abused substances but have unpredictable toxicity. One of these drugs is gacyclidine, a derivative of phencyclidine (PCP). Gacyclidine has been studied as a neuroprotective agent in trauma and as a therapy of soman toxicity. There are no previous reports of its use as a drug of abuse. CASE REPORTS During a two-month period in the summer of 2013, a series of patients with severe agitation and end-organ injury were identified in an urban academic Emergency Department (ED). A urine drug of abuse screen was performed on all patients, and serum samples were sent for comprehensive toxicology analysis. A total of five patients were identified as having agitation, rhabdomyolysis, and elevated troponin (Table 1). Three of the five patients reported use of methamphetamine, and all five patients had urine drug screens positive for amphetamine. Comprehensive serum analysis identified methamphetamine in three cases, cocaine metabolites in one case, and a potential untargeted match for gacyclidine in all five cases. No other drugs of abuse were identified. DISCUSSION This is the first series of cases describing possible gacyclidine intoxication. The possible source of the gacyclidine is unknown but it may have been an adulterant in methamphetamine as all patients who were questioned reported methamphetamine use. These cases highlight the importance of screening for new drugs of abuse when patients present with atypical or severe symptoms. Gacyclidine has the potential to become a drug of abuse both by itself and in conjunction with other agents and toxicity from gacyclidine can be severe. It is the role of the medical toxicology field to identify new agents such as gacyclidine early and to attempt to educate the community on the dangers of these new drugs of abuse.

Nicotine-dependence-varying effects of smoking events on momentary mood changes among adolescents. Addict Behav 2015; 41:65-71.

Abstract
INTRODUCTION Theories of nicotine addiction emphasize the initial role of positive reinforcement in the development of regular smoking behavior, and the role of negative reinforcement at later stages. These theories are tested here by examining the effects of amount smoked per smoking event on smoking-related mood changes, and how nicotine dependence (ND) moderates this effect. The current study examines these questions within a sample of light adolescent smokers drawn from the metropolitan Chicago area (N=151, 55.6% female, mean 17.7years). INSTRUMENTS Ecological momentary assessment data were collected via handheld computers, and additional variables were drawn from a traditional questionnaire. METHODS Effects of the amount smoked per event on changes in positive affect (PA) and negative affect (NA) after vs. before smoking were examined, while controlling for subject-averaged amount smoked, age, gender, and day of week. ND-varying effects were examined using varying effect models to elucidate their change across levels of ND. RESULTS The effect of the amount smoked per event was significantly associated with an increase in PA among adolescents with low-to-moderate levels of ND, and was not significant at high ND. Conversely, the effect of the amount smoked was significantly associated with a decrease in NA only for adolescents with low levels of ND. CONCLUSIONS These findings support the role of positive reinforcement in early stages of dependent smoking, but do not support the role of negative reinforcement beyond early stages of smoking. Other potential contributing factors to the relationship between smoking behavior and PA/NA change are discussed.

What is the evidence for hardening in the cigarette smoking population? Trends in nicotine dependence in the U.S., 2002-2012. Drug Alcohol Depend 2014; 142:333-40.

Abstract
BACKGROUND It is unclear whether declines in cigarette smoking in the U.S. have resulted in a hardened population of "hardcore" smokers. We studied changes in nicotine dependence severity from 2002 to 2012, using data from the National Survey on Drug Use and Health. METHODS We used generalized non-linear factor analysis to examine whether individual Nicotine Dependence Syndrome Scale (NDSS) items functioned differently over time, and whether average NDSS scores changed in a sample of 130,637 current smokers. We also examined trends for individual NDSS sub-scales and whether trends were moderated by tobacco consumption and socio-demographic factors. RESULTS Consumption levels and dependence severity both declined over the study period. This decline was driven by priority (e.g., avoiding smoke-free locations) and tolerance dimensions of dependence, while drive (e.g., craving and smoking to relieve negative affect) and continuity (e.g., stability) of smoking did not change. Declines for tolerance were greatest among those without serious psychological distress and among middle-aged smokers. Drive and continuity increased among women and low income smokers. CONCLUSIONS We did not find evidence of hardening at the population level for smokers in the U.S., 2002-2012. However, there is evidence of hardening when considering drive and continuity-related nicotine dependence among women and low-income smokers, suggesting these sub-groups are experiencing greater severity of craving, smoking to relieve negative affect, and regularity of smoking despite reduced consumption.

Abstract
INTRODUCTION Maternal smoking during pregnancy (MSP) is a known risk factor for regular smoking in young adulthood and may pose a risk independently of mother's lifetime smoking. The processes through which MSP exerts this influence are unknown but may occur through greater smoking quantity and frequency following initiation early in adolescence or increased sensitivity to nicotine dependence (ND) at low levels of smoking. METHODS This study used path analysis to investigate adolescent smoking quantity, smoking frequency, and ND as potential simultaneous mediating pathways through which MSP and mother's lifetime smoking (whether she has ever smoked) increase the risk of smoking in young adulthood among experimenters (at baseline, <100 cigarettes/lifetime) and current smokers (>100 cigarettes/lifetime). RESULTS For experimenters, MSP was directly associated with more frequent young adult smoking and was not mediated by adolescent smoking behavior or ND. Independently of MSP, the effect of mother's lifetime smoking was fully mediated through frequent smoking and was heightened ND during adolescence. Controlling for MSP eliminated a previously observed direct association between mother's lifetime smoking and future smoking among experimenters. For current smokers, only prior smoking behavior was associated with future smoking frequency. CONCLUSIONS These results seem to rule out sensitivity to ND and increased smoking behavior as contributing pathways of MSP. Further, the impact of MSP on young adult smoking extends beyond that of having an ever-smoking mother. Future work should test other possible mediators; for example, MSP-related epigenetic changes or gene variants influencing the brain's nicotine response.

Abstract
INTRODUCTION Research identifying nicotine dependence (ND) symptoms most appropriate for measurement of adolescent ND and invariant across the range of smoking exposure is hampered by limited sample size and variability of smoking behavior within independent studies. Integrative data analysis, the process of pooling and analyzing data from multiple studies, produces larger and more heterogeneous samples with which to evaluate measurement equivalence across the full continuum of smoking quantity and frequency. METHODS Data from two studies were pooled to obtain a large sample of adolescent and young adult smokers with considerable variability in smoking. We used moderated nonlinear factor analysis, which produces study equivalent ND scores, to simultaneously evaluate whether 14 DSM ND symptoms had equivalent psychometric properties (1) at different levels of smoking frequency and (2) across a continuous range of smoking quantity, after accounting for study differences. RESULTS Nine of 14 symptoms were equivalent across levels of smoking frequency and quantity in probability of endorsement at different levels of ND and in ability to discriminate between levels of ND severity. A more precise ND factor score accounted for study and smoking related differences in symptom psychometric properties. CONCLUSIONS DSM-IV symptoms may be used to reliably assess ND in young populations across a wide range of smoking quantity and frequency and within both nationally representative and geographically restricted samples with different study designs. Symptoms shared across studies produced an equivalently scaled ND factor score, demonstrating that integrating data for the purpose of studying ND in young smokers is viable.

[PMID: 22995764 PMCID: PMC3538104 DOI: 10.1016/j.drugalcdep.2012.08.026] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2012] [Revised: 08/01/2012] [Accepted: 08/28/2012] [Indexed: 11/24/2022]
Abstract
BACKGROUND Little is known about time-varying effects of smoking quantity and nicotine dependence on the regularity of adolescent smoking behavior. METHODS The sample was drawn from the Social and Emotional Contexts of Adolescent Smoking Patterns Study which followed adolescent smokers over 5 assessment waves spanning 48 months. Participants included former experimenters (smoked <100 cigarettes/lifetime but did not smoke in past 90 days), recent experimenters (smoked <100 cigarettes/lifetime and smoked in past 90 days), and current smokers (smoked >100 cigarettes/lifetime and smoked in past 30 days). Mixed-effects regression models were run to examine the time-varying effects of smoking quantity and nicotine dependence on regularity of smoking behavior, as measured by number of days smoked. RESULTS Smoking quantity and nicotine dependence were each found to be significantly associated with regularity of adolescent smoking and the size of each effect exhibited significant variation over time. The effect of smoking quantity decreased across time for each smoking group, while the effect of nicotine dependence increased across time for former and recent experimenters. By the 48-month follow-up, the effects of smoking quantity and nicotine dependence had each stabilized across groups. CONCLUSIONS This study reveals that smoking quantity and nicotine dependence are not static risk factors for the development of more regular smoking patterns. At low levels of smoking when nicotine dependence symptoms are less common, smoking quantity is a stronger predictor of increased regularity of smoking, while for more experienced smokers, nicotine dependence predicts further increases in regularity.

Test-retest reliability of the eating disorder examination-questionnaire (EDE-Q) in a college sample. J Eat Disord 2013; 1:42. [PMID: 24999420 PMCID: PMC4081765 DOI: 10.1186/2050-2974-1-42] [Citation(s) in RCA: 70] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2013] [Accepted: 11/07/2013] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND The Eating Disorder Examination-Questionnaire (EDE-Q), a widely used self-report instrument, is often used for measuring change in eating disorder symptoms over the course of treatment. However, limited data exist about test-retest reliability, particularly for men. The current study evaluated EDE-Q 7-day test-retest reliability in male (n = 47) and female (n = 44) undergraduate students together and separately by gender. RESULTS Internal consistency was consistently higher for women and at Time 2, but remained acceptable for both men and women at both time points. Cronbach's α ranged from .75 (Restraint at Time 1) to .93 (Shape Concern at Time 2) for women and from .73 (Eating Concern at Time 2) to .89 (Shape Concern at Time 2) for men. With the exception of some of the eating disorder behaviors, test re-test reliability was fairly strong for both men and women. Shape Concern and the global EDE-Q score were highest for both men and women (Spearman's rho > 0.89 with the exception of Shape Concern for women for which Spearman's rho = .86). Test re-test reliability was lower for the eating disorder behavior measures, particularly for men, for whom Kendall's tau-b for frequency and phi for occurrence was less than 0.70 for all but objective bulimic episodes. CONCLUSIONS Results were consistent with past research for women, indicating strong test re-test reliability in attitudinal features of eating disorders, but lower test re-test reliability in behavioral features. Internal consistency and test re-test reliability was good for the attitudinal features of eating disorder in men, but tended to be lower for men compared to women. The EDE-Q appears to be a reliable instrument for assessing eating disorder attitudes in both male and female undergraduate students, but is less reliable for assessing ED behaviors, particularly in men.

Adolescent nicotine dependence symptom profiles and risk for future daily smoking. Addict Behav 2012; 37:1093-100. [PMID: 22673155 DOI: 10.1016/j.addbeh.2012.05.004] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2011] [Revised: 05/09/2012] [Accepted: 05/15/2012] [Indexed: 10/28/2022]
Abstract
Recent research on adolescent smokers suggests that there are important differences in the types of nicotine dependence (ND) symptoms that emerge and different patterns of ND symptoms. The purpose of this study was to use data from the longitudinal Social and Emotional Contexts of Adolescent Smoking Patterns Study to identify latent subgroups of adolescent experimental and nondaily smokers varying in number and types of endorsed ND symptoms. Profiles were identified using baseline level of smoking, individual patterns of ND symptoms and other ND risk factors. Discrete time survival analysis was used to examine profile differences in probability of becoming daily smokers 48 months later. Four distinct subgroups of smokers with different patterns of smoking behavior, ND symptoms, and alcohol and other substance use emerged. Heavier smoking adolescents with high symptom endorsement, particularly the need to smoke in the morning, were most likely to become daily smokers 48 months later. A subgroup of social smokers had high smoking exposure and symptom endorsement (except need to smoke in the morning), and high levels of other substance use. Despite lower rates of smoking frequency and quantity compared to the heavier smoking class, 36% of these adolescents smoked daily by 48 months, with a steeper decline in survival rates compared to other lighter smoking classes. Morning smoking symptoms and symptoms prioritizing smoking (i.e., choosing to spend money on cigarettes instead of lunch or smoking when ill or where smoking is forbidden) might quickly identify adolescent non-daily smokers with more severe dependence and higher risk for daily smoking. A focus on skills for avoiding social situations involving use of alcohol and other drugs and reducing peer smoking influences may be an important focus for reducing smoking and other substance use among social smokers.

A Practical Guide to Calculating Cohen's f(2), a Measure of Local Effect Size, from PROC MIXED. Front Psychol 2012; 3:111.

Abstract
Reporting effect sizes in scientific articles is increasingly widespread and encouraged by journals; however, choosing an effect size for analyses such as mixed-effects regression modeling and hierarchical linear modeling can be difficult. One relatively uncommon, but very informative, standardized measure of effect size is Cohen's f(2), which allows an evaluation of local effect size, i.e., one variable's effect size within the context of a multivariate regression model. Unfortunately, this measure is often not readily accessible from commonly used software for repeated-measures or hierarchical data analysis. In this guide, we illustrate how to extract Cohen's f(2) for two variables within a mixed-effects regression model using PROC MIXED in SAS(®) software. Two examples of calculating Cohen's f(2) for different research questions are shown, using data from a longitudinal cohort study of smoking development in adolescents. This tutorial is designed to facilitate the calculation and reporting of effect sizes for single variables within mixed-effects multiple regression models, and is relevant for analyses of repeated-measures or hierarchical/multilevel data that are common in experimental psychology, observational research, and clinical or intervention studies.

Abstract
INTRODUCTION Few studies have investigated the natural course of nicotine dependence prospectively from the earliest experiences with smoking. METHODS Drawing on a cohort of 9th- and 10th-grade adolescents followed over 48 months, survival analyses were conducted to evaluate the cumulative probability, following smoking initiation, for the development of nicotine dependence symptoms. RESULTS Although each nicotine dependence symptom was significantly more prevalent among adolescents who had smoked more than 100 cigarettes by the end of the follow-up assessment, 20% of adolescents smoking fewer than 100 cigarettes reported experiencing "smoking to relieve restlessness and irritability" and "smoking a lot more now to be satisfied compared to when first smoked." Nicotine dependence symptoms were also reported before reaching 100 cigarettes for a substantial number of adolescents (between 9.4% and 58.8% for individual symptoms). Endorsement of nicotine dependence symptoms prospectively predicted past-week smoking (odds ratios [ORs] between 3.18 and 14.62 for significant symptoms) and past-month daily smoking (significant symptoms' ORs between 3.52 and 10.68) at the 48-month assessment even when controlling for amount of previous smoking. CONCLUSIONS The present study adds to the growing body of literature on the natural course of nicotine dependence from earliest experiences with smoking by showing that symptoms of nicotine dependence may develop soon after initiation and/or at low levels of smoking. Our findings suggest that novice adolescent smokers should not be neglected in smoking cessation intervention and that screening and effective intervention for early emerging symptoms among adolescent smokers may be an important target in preventing chronic smoking.

Alcohol dependence symptoms among recent onset adolescent drinkers. Addict Behav 2011; 36:1160-7. [PMID: 21835550 PMCID: PMC3296118 DOI: 10.1016/j.addbeh.2011.07.014] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2010] [Revised: 04/04/2011] [Accepted: 07/14/2011] [Indexed: 10/17/2022]
Abstract
This study examined prevalence of alcohol dependence symptoms and diagnosis among a nationally representative sample of recent onset adolescent drinkers aged 12-21 years (mean 17 years) across different levels of drinking drawn from National Survey of Drug Use and Health (N=9490). We assessed whether the relationship between level of alcohol use and alcohol dependence was similar for individuals from different socio-demographic groups (i.e., gender, age group, ethnic group, family income, and substance use in the past year). The most prevalent DSM-IV alcohol dependence criteria at low levels of alcohol use were "unsuccessful efforts to cut down", "tolerance", and "time spent" in activities necessary to obtain alcohol or recover from its effect. Logistic regression with polynomial contrasts indicated increasing rates of each criterion and an overall dependence diagnosis with increasing alcohol exposure that differed most between the lowest levels of recent drinking frequency. After controlling for drinking quantity, younger adolescents, females, Native American/Alaskans and Asian/Pacific Islanders were most likely to experience alcohol dependence symptoms and a diagnosis of dependence, suggesting that these demographic subgroups may experience dependence symptoms or develop dependence more quickly after beginning to drink. Recognizing early symptoms of alcohol dependence may assist in early identification and intervention of those at risk for heavier drinker in the future.

Alcohol use as a signal for sensitivity to nicotine dependence among recent onset smokers. Addict Behav 2011; 36:421-6.

Abstract
OBJECTIVE This study evaluated the association between alcohol use, abuse and dependence and cigarette smoking to determine whether alcohol may signal greater sensitivity to nicotine dependence at very low levels of smoking. METHOD Data were drawn from five annual National Surveys on Drug Use and Health and included individuals age 12 to 21 who reported first exposure to smoking within the past two years and smoking at least once in the past month. RESULTS Both alcohol abuse and alcohol dependence were associated with increased likelihood of symptoms that seem to tap tolerance for nicotine. These included items such as "the amount you smoke has increased"; "needing to smoke a lot more now in order to be satisfied"; and "smoking much more before starting to feel anything". Alcohol dependence, but not abuse was associated with the remaining symptoms, "after not smoking for a while, needing to smoke to feel less restless and irritable"; "craving cigarettes after not smoking for a while"; and "worrying about running out of cigarettes". All associations were not better accounted for by either alcohol use or amount smoked. CONCLUSION If causally associated, treatment of alcohol-use disorders may prevent or reduce the early emergence of nicotine dependence symptoms among new smokers, very early in the smoking uptake process. If instead alcohol disorders are a signal of sensitivity for nicotine dependence best accounted for by a third variable, then adolescents with alcohol dependence and/or abuse during early exposures to smoking represents an important subgroup that may benefit from interventions directly targeting this association.

Abstract
OBJECTIVE To estimate prevalence of childhood ADHD among incarcerated women and determine its association with substance use and adult functioning. METHOD 192 female participants are recruited from the Department of Corrections in Rhode Island. Childhood ADHD is defined as scoring >46 on the Wender Utah Rating Scale. RESULTS The findings reveal that 46% met criteria for childhood ADHD. Multivariate analysis reveal that women meeting WURS criteria were more likely to be inconsistently employed (OR = 0.23, 95% CI = 0.10-0.54), recently homeless (OR = 2.09, 95% CI = 1.02-4.30), lifetime incarceration of more than 90 days (OR = 3.00, 95% CI = 1.37-6.57), current smokers (OR = 2.99, 95% CI = 1.24-7.20), and ever used marijuana regularly (OR = 3.47, 95% CI = 1.61-7.45). CONCLUSION Among incarcerated women, childhood ADHD is associated with negative social and health behaviors.

Abstract
INTRODUCTION Given absence of a "gold standard" for measuring self-reported nicotine dependence, particularly among less experienced smokers, there is a need to evaluate existing measures to determine how well symptoms measure the underlying nicotine dependence construct and whether symptoms function differently for less experienced smokers. Study aims were to determine (1) likelihood of endorsement of individual symptoms at different levels of a nicotine dependence construct and the ability of symptoms to discriminate between different levels of this construct and (2) whether these symptom properties varied between nondaily and daily smokers. METHODS We used multiple group item response theory analysis to evaluate nicotine dependence symptoms from the nicotine dependence syndrome scale based on a nationally representative sample of 8081 recent onset adolescent smokers from the national surveys on drug use and health. RESULTS After controlling for age, gender, smoking quantity and length of smoking exposure, symptoms assessing tolerance were invariant across nondaily and daily smokers, and discriminated well between levels of the nicotine dependence construct. However, the majority of symptoms functioned differently for nondaily and daily smokers. These symptoms did not discriminate as well between levels of the nicotine dependence construct and were more likely to be endorsed at lower levels of this construct for daily smokers. DISCUSSION A measure that encompasses a range of symptoms tapping different aspects of smoking may be ideally suited for nondaily adolescent smokers, while an ideal measure of nicotine dependence for daily smokers might also include more core diagnostic features of nicotine dependence such as withdrawal and tolerance.

Abstract
INTRODUCTION This study evaluated how well DSM-IV nicotine dependence symptoms measure an underlying dependence construct for recent-onset daily and nondaily smokers. METHODS Based on a nationally representative sample of 2,758 recent-onset adolescent smokers from the National Surveys on Drug Use and Health, we used multiple group item response theory analysis to assess 7 symptoms representing DSM-IV diagnostic features of nicotine dependence. RESULTS After controlling for age, gender, current smoking quantity, and length of smoking exposure, all 7 DSM-IV symptoms were invariant across nondaily and daily smokers and discriminated well among levels of the nicotine dependence construct. Symptoms most likely to be endorsed at lower levels of the dependence construct included spending more time getting, using, or getting over the effects of smoking and wanting or trying to stop or cut down. Symptoms most likely to be endorsed only at higher levels of the construct included giving up important activities and emotional/psychological and health problems related to smoking. DSM-IV symptoms were most precise for moderately high levels of the dependence construct and less precise for lower levels for both nondaily and daily smokers. DISCUSSION DSM-IV nicotine dependence symptoms appear to have desirable psychometric properties for measuring a nicotine dependence construct among recent-onset adolescent smokers at both daily and nondaily levels, providing justification for the use of these symptoms in a measure that aims to evaluate the full continuum of nicotine dependence severity in this population.

Abstract
The present study examined the prevalence of individual nicotine dependence symptoms among recent onset smokers across the continuum of nondaily and daily cigarette smoking behavior in a nationally representative sample of recent onset smokers from the National Surveys on Drug Use and Health (NSDUH). Rates of endorsement for 17 symptoms drawn primarily from the Nicotine Dependence Symptom Scale (Shiffman et al., 2004) were calculated for four levels of nondaily (smoked 1-3, 4-10, 11-20, or 21-29 days in the past 30 days) and daily (smoked 1, 2-5, 6-15, or >15 cigarettes per day in the past 30 days) smoking. Logistic and linear regression analyses with polynomial contrasts controlling for age, gender, length of exposure, and smoking quantity tested trends in symptom endorsement across levels of smoking. Significant linear and quadratic trends indicated that increasing rates of endorsement differed most between the lowest levels of nondaily and daily smoking. Results suggest that, for some, infrequent smoking may not represent benign experimentation. Recognizing early symptoms of nicotine dependence may assist in early identification and intervention of those at risk for heavier smoking in the future. Adolescents can be taught to recognize the early symptoms of nicotine dependence to increase awareness of the rapidity at which these symptoms may appear.

Abstract
This study extends research on the association between smoking behavior and chronic disease by following a cohort from the time of initiation of regular smoking patterns into old age and by examining the association of lifetime smoking trajectories with chronic disease and mortality. Participants consisted of 232 males selected from the Harvard classes of 1942-1944 and followed biennially through 2003. Five distinct smoking trajectories were identified based on the age at which participants quit daily smoking. Participants following smoking trajectories with later cessation had a higher likelihood of developing lung disease and lived shorter lives than those who quit smoking at an earlier age. This study confirms that the earlier a smoker quits, the greater the health benefits, and that these benefits are observed even decades after smoking cessation. Additionally, by showing different survival rates between trajectory groups 25 and 40 years after quitting, the results run counter to previous work that has found no difference in mortality between smokers and non-smokers 15 years after cessation.

Abstract
OBJECTIVE To explore patterns of persistence and change in smoking behavior as well as risk factors associated with the developmental course of smoking from age 13 to 25. DESIGN Data from the public use sample of the National Longitudinal Study of Adolescent Health (N = 5,789) were analyzed using semiparametric group-based modeling. MAIN OUTCOME MEASURES Smoking quantity-frequency in the past 30 days. RESULTS Six distinct smoking trajectories were identified: nonsmokers, experimenters, stable light smokers, quitters, late escalators, and stable high smokers. Baseline risk factors that were associated with greater likelihood of membership in all of the smoking trajectory groups compared with nonsmokers included alcohol use, deviance, peer smoking, and (with the exception of the late escalators) drug use. Deviance, peer smoking, and alcohol and drug use also distinguished the likelihood of membership among several of the 5 smoking trajectory groups. CONCLUSION The results add to basic etiologic research on developmental pathways of smoking in adolescence and young adulthood by providing evidence of heterogeneity in smoking behavior and prospectively linking different patterns of risk factors with the probability of trajectory group membership.

Abstract
BACKGROUND Trazodone is a commonly prescribed off-label for sleep disturbance in alcohol-dependent patients, but its safety and efficacy for this indication is unknown. METHODS We conducted a randomized, double-blind, placebo-control trial of low-dose trazodone (50 to 150 mg at bedtime) for 12 weeks among 173 alcohol detoxification patients who reported current sleep disturbance on a validated measure of sleep quality or during prior periods of abstinence. Primary outcomes were the proportion of days abstinent and drinks per drinking day over 6-months; sleep quality was also assessed. RESULTS Urn randomization balanced baseline features among the 88 subjects who received trazodone and 85 who received placebo. The trazodone group experienced less improvement in the proportion of days abstinent during administration of study medication (mean change between baseline and 3 months: -0.12; 95% CI: -0.15 to -0.09), and an increase in the number of drinks per drinking day on cessation of the study medication (mean change between baseline and 6 months, 4.6; 95% CI: 2.1 to 7.1). Trazodone was associated with improved sleep quality during its administration (mean change on the Pittsburgh Sleep Quality Index between baseline and 3 months: -3.02; 95% CI: -3.38 to -2.67), but after it was stopped sleep quality equalized with placebo. CONCLUSIONS Trazodone, despite a short-term benefit on sleep quality, might impede improvements in alcohol consumption in the postdetoxification period and lead to increased drinking when stopped. Until further studies have established benefits and safety, routine initiation of trazodone for sleep disturbance cannot be recommended with confidence during the period after detoxification from alcoholism.

Abstract
Rates of sexually transmitted infections (STIs) in women in U.S. corrections facilities are higher than rates in community samples. Research that combines behavioral correlates of STI with STI history by race/ethnicity has not been done in incarcerated women. The purpose of this study was to compare by race/ethnicity self-reported sexual risk behaviors with self-reported history of STI in an incarcerated sample. An interviewer administered a questionnaire to 428 incarcerated women. Blacks were more likely to report consistent condom use in the three months prior to incarceration (47% vs. 28%, p < 0.05), and Hispanics were less likely to report sex work than were whites (16% vs. 39%, p < 0.05). Whites were more likely than blacks to report having had an unplanned pregnancy (88% vs. 67%, p < 0.05). Despite having lower self-reported risk on several measures, Blacks were more likely to report history of STI (65% vs. 40%, p < 0.05). The correctional setting is an opportune place to better understand and address the complex issue of sexual health disparities.

Abstract
This study used semi-parametric group-based modeling to explore unconditional and conditional trajectories of self-reported depressed mood from ages 12 to 25 years. Drawing on data from the National Longitudinal Study of Adolescent Health (N = 11,559), 4 distinct trajectories were identified: no depressed mood, stable low depressed mood, early high declining depressed mood, and late escalating depressed mood. Baseline risk factors associated with greater likelihood of membership in depressed mood trajectory groups compared with the no depressed mood group included being female, Black or African American, Hispanic or Latino American, or Pacific Islander or Asian American; having lower socioeconomic status; using alcohol, tobacco, or other drugs on a weekly basis; and engaging in delinquent behavior. Baseline protective factors associated with greater likelihood of membership in the no depressed mood group compared with the depressed mood trajectory groups included 2-parent family structure; feeling connected to parents, peers, or school; and self-esteem. With the exception of delinquent behavior, risk and protective factors also distinguished the likelihood of membership among several of the 3 depressed mood groups. The results add to basic etiologic research regarding developmental pathways of depressed mood in adolescence and young adulthood.

OBJECTIVES This study sought to identify correlates of acceptance of a hypothetical Neisseria gonorrhea (GC) vaccine in a high-risk sample of incarcerated women. GOALS The goal of this study was to inform efforts to promote acceptance of STI vaccines in development. STUDY DESIGN This study consisted of a cross-sectional survey using a structured questionnaire. RESULTS The majority (79%) of incarcerated women surveyed would accept GC vaccine. In multivariate analyses that controlled for demographics, significant health belief model psychosocial correlates of higher acceptance were perceived severity of infection (OR = 3.33) and vulnerability to infection (OR = 2.85). Fear of vaccination was significantly correlated with lower acceptance (OR = 0.42). CONCLUSIONS Incarcerated women's willingness to accept a hypothetical GC vaccine is explained by components of the health belief model and a component of the theory of reasoned action.

AIMS Despite aggressive anti-smoking campaigns, smoking rates are increasing among young women, suggesting the need for new approaches to reach this population. Segmenting audiences can facilitate targeting interventions to specific populations, based on association of smoking behaviors with other health behaviors and psychological and social antecedents. Using latent class analysis, we sought to profile patterns of behavioral, attitudinal and cognitive variables related to tobacco use among young women. DESIGN This study is part of an ongoing Midwestern longitudinal self-report survey of the natural history of cigarette smoking. PARTICIPANTS Participants were 18-25-year-old women smokers (n = 443). MEASUREMENTS Variables included a comprehensive range of demographic characteristics, smoking-related variables and general attitudinal variables. FINDINGS Three distinct classes emerged with the following characteristics: (1) working women who tended to smoke daily but reported high levels of positive affect and life satisfaction (n = 212); (2) light-smoking college students who exercised regularly, began smoking after high school and quit successfully at follow-up 5 years later (n = 86); and (3) heavy smokers who were more likely to have children, report high levels of negative affect and smoke for addictive reasons, for stimulation and to control affect (n = 145). Differences in smoking cessation at a 5-year follow-up were significant across the classes (18.1%, 34.4% and 13.0% had quit for at least 6 months, respectively). CONCLUSIONS The psychosocial and behavioral profiles of these classes can potentially be used to tailor smoking interventions more effectively within this population.

Marijuana use among young women in a primary care setting. J Gen Intern Med 2007; 22:826-9. [PMID: 17372785 PMCID: PMC2219851 DOI: 10.1007/s11606-007-0168-6] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/11/2006] [Revised: 02/01/2007] [Accepted: 02/12/2007] [Indexed: 10/23/2022]
Abstract
OBJECTIVE To evaluate the prevalence of marijuana use among young women, ages 18-24, within a primary care setting. DESIGN From 2/05 to 12/05, women completed a brief, anonymous self-report screening instrument in two urban primary care clinics for potential participation in a randomized controlled trial of an intervention to reduce marijuana use and sexual risk-taking behavior. During the last few months of recruitment, women who completed the screening instrument were also asked to provide a urine sample to test for the presence of marijuana and other drugs. RESULTS Of the 607 women who completed the screening instrument, 38.6% reported lifetime marijuana use, 8.4% used marijuana at least monthly, and 1.7% reported using marijuana daily. Within this ethnically diverse sample (45% Hispanic), women who used marijuana at least monthly were more likely to smoke cigarettes (OR = 2.03, 95% CI = 1.04, 3.96), binge drink at least once a month (OR = 2.66, 95% CI = 1.34, 5.28), and to have ever used other drugs (OR = 2.91, 95% CI = 1.31, 6.45). Of the 67 urine samples provided, 60 (89.6%) were concordant with self-reported use, but six of the seven discordant samples were positive despite negative self-report. CONCLUSIONS The prevalence of marijuana use and binge drinking in this ethnically diverse sample of young, female primary care patients was lower than rates reported in national surveys. Providers should consider marijuana use as a part of a process that addresses more prevalent high-risk behaviors, bearing in mind that these behaviors may be underreported during routine screening.

Abstract
An increasing number of women are involved in the criminal justice system. Women in corrections are often of low socioeconomic status, medically underserved and exposed to a variety of traumatic events. Programs and services provided in correctional settings should be informed by the unique profiles and needs of these women. This study sought to identify distinct sub-groups (classes) of incarcerated women based on differences in their qualitative (types of trauma) and quantitative (number of) trauma experiences. Demographics, psychosocial and behavioral characteristics were measured in 149 women entering jail, who reported recent hazardous drinking and HIV sexual risk behavior. Two classes based on trauma exposure of women were identified through latent class analysis. The classes did not differ with respect to qualitative differences in trauma exposure (both classes reported all forms of trauma), but did differ with respect to quantitative differences (Class 2 reported more exposure to trauma in all categories than Class 1). The classes also differed significantly on current psychological functioning, alcohol treatment, problems, and consequences, drug histories, sexual risk, medical conditions, and social group characteristics. In all areas, members of Class 2 were significantly more likely to report higher levels of measured variables. Nearly all women in our sample reported levels of trauma exposure, suggesting a need for intervention and attention. Through identifying these separate classes, limited resources for trauma survivors in the correctional setting could be most appropriately allocated.

Abstract
OBJECTIVES Women in correctional institutions have substantial reproductive health problems, yet they are underserved in receipt of reproductive health care. We assessed the level of risk for sexually transmitted diseases (STDs) and the reproductive health needs of 484 incarcerated women in Rhode Island to plan an intervention for women returning to the community. METHODS We used a 45-minute survey to assess medical histories, pregnancy and birth control use histories, current pregnancy intentions, substance use during the past 3 months, histories of childhood sexual abuse, and health attitudes and behaviors. RESULTS Participants had extremely high risks for STDs and pregnancy, which was characterized by inconsistent birth control (66.5%) and condom use (80.4%), multiple partners (38%), and a high prevalence of unplanned pregnancies (83.6%) and STDs (49%). Only 15.4% said it was not likely that they would have sexual relations with a man within 6 months after release. CONCLUSION Reproductive health services must be offered to incarcerated women. Such interventions will benefit the women, the criminal justice systems, and the communities to which the women will return.

Abstract
OBJECTIVES We examined whether incarcerated women would substantially increase birth control initiation if contraceptive services were available within the prison compared with after their release back into the community. METHODS During phase 1 of the study, a nurse educator met with women at the Rhode Island Adult Correctional Institute and offered them referrals for contraceptive services at a community health clinic after their release. During phase 2, contraceptive services were offered to women during their incarceration. RESULTS The majority of the participants (77.5%) reported a desire to initiate use of birth control methods. Within 4 weeks of their release, 4.4% of phase 1 participants initiated use of a contraceptive method, compared with 39.1% of phase 2 participants (odds ratio [OR]=14.6; 95% confidence interval [CI]=5.5, 38.8). CONCLUSIONS Provision of contraceptive services to women during their incarceration is feasible and greatly increases birth control initiation compared to providing services only in the community.

Abstract
Dental care can occur within or outside the formal health-care system. We hypothesized that certain subject characteristics would partly explain one type of dental self-care, non-professional extractions. A representative sample of diverse groups of dentate adults was studied. In-person interviews and clinical examinations were conducted at baseline, 24, 48, and 72 months, with semi-annual telephone interviews in between. Of 699 participants, 291 (42%) reported loss of at least one tooth, of whom 42 (14% of those with tooth loss) reported having lost the tooth at a place other than a health-care facility. Ninety-four percent of non-professionally lost teeth were self-extracted; relatives extracted the remainder. Fifty-eight percent of these teeth were deliberately removed; the remainder came out while subjects were eating or brushing their teeth, or due to injury. Attachment loss and mobility at previous examination were consistent with the occurrence of non-professional extraction. The incidence magnitude was substantive and persistent throughout follow-up.

Abstract
The current study used a cohort-sequential design to examine age-related changes in health-relevant beliefs from the middle school years through age 37 in a large, midwestern, community sample (N=8,556). Results suggest systematic age-related changes such that beliefs in the personalized risks of smoking declined in middle school and then increased, beliefs in generalized health risks increased beginning in the middle school years, and values placed on health as an outcome decreased in the high school years and then increased. These findings suggest that intervention programs must counter declining personalized risk perceptions among middle school students and declining values placed on health among high school age students.

Abstract
A number of clinical coding and vocabulary schemes are in use in healthcare enterprises today. Most of them are weak in light of the qualities that characterize adequate controlled medical terminologies, as outlined in Part One of this review. Here we look at the major code and terminology sets with a critical eye, as well as suggest practical steps to enable health industry information system purchasers and users to move forward with their effort to use common terminology to improve the quality, service, and knowledge in their enterprise.

Abstract
It has become abundantly clear that standards of recording clinical terms in human-readable, computer-processable format are indispensable. Controlled medical terminology is the missing link in health information standards (in fact, medical terminology can be viewed as the mother of all standards); its absence interferes with the business of healthcare and impedes the core processes of healing and maintaining health. Medicine has lacked the controlled common medical vocabulary that would enable universal sharing of data at the point of care and ensure reliable information for determining health intervention effectiveness. Simple clinical and code content alone has proven insufficient for healthcare enterprises to successfully manage the terminology problem; the "lexical runtime engine," formerly called a vocabulary server (VOSER), which manages the vocabulary ontology and serves up the relevant vocabulary to users of applications in the clinical environment, has recently become a reality.

Abstract
OBJECTIVE To determine the physiological consequences of acute CO exposure from cooking in snow caves at 3,200 m. We hypothesized that ambient CO and serum carboxyhemoglobin (COHb) levels would increase and that even low levels of COHb would be associated with symptoms of CO poisoning at high altitude. METHOD This was a prospective observational study. Twenty-two healthy volunteers age 18 years or older were recruited during a winter camping trip at 3,200 m. Subjects filled out symptom questionnaires, and heart rate (HR), oxygen saturation (SaO2), serum COHb, and ambient CO were all measured before and after cooking inside snow caves. RESULTS Median age of subjects was 32 years, and 87% were male. The median ambient CO level increased by 17 ppm (IQR, 2-27 ppm), P = .005. Mean serum COHb level rose from 0.3% (IQR, 0.2%-0.4%) to 1.2% (IQR, 0.7%-2.6%) after cooking, for a difference of 1% (IQR, 0.4%-2.3%), P < .001. There were no differences in symptom scores before and after cooking, and there was no significant effect on HR or SaO2. CONCLUSION A single exposure to CO at 3,200 m increases ambient CO and COHb but not to clinically important levels. Further studies are needed to examine the risks of longer exposures at higher altitudes.

Abstract
OBJECTIVE There is a paucity of evidence demonstrating that emergency department (ED) ultrasound changes clinical practice in trauma patients. We hypothesized that the presence of ultrasound would affect clinical decision making as evidenced through abdominal computed tomographic (CT) scan use in blunt multiple trauma patients. METHODS This study used a prospective randomized format in an urban county ED with Level II trauma center status (ED census, 72,000 patients per year). Participants were patients with multiple blunt injuries meeting trauma center triage criteria. Patients were randomized to receive either abdominal ultrasound or no ultrasound (control) during initial ED resuscitation. The primary outcome variable was use of abdominal CT scan in patients with and without ultrasound. RESULTS Two hundred eight patients were enrolled. The mean age was 40 +/- 18 years, and 62% were men. Mechanism of injury was motor vehicle crash, 56%; automobile versus pedestrian, 18%; motorcycle crash, 16%; falls, 10%; and other, 10%. One hundred four ultrasound and 104 control patients were analyzed. There were no apparent differences between ultrasound and control groups in demographics, injury type, or Injury Severity Score. Fifty-four of 104 (52%) of the control group received abdominal CT scans versus 37 of 104 (36%) abdominal CT scans for the ultrasound group; mean difference in proportions was 15.9 (p < 0.01; 95% confidence interval, 2.6-29.1). CONCLUSION In this trial, the routine use of abdominal ultrasound in the evaluation of patients with multiple blunt injuries resulted in significantly fewer abdominal CT scans being obtained. A larger trial is needed to more clearly define the clinical and financial impact of ultrasound in the management of blunt abdominal trauma.

Abstract
This report describes a novel sonographic protocol for the evaluation of the undifferentiated hypotensive patient. This protocol combines components of 3 sonographic applications: free fluid, cardiac, and abdominal aorta into a single protocol. We believe this protocol and its underlying principles should be a routine part of the empiric evaluation of the patient with undifferentiated hypotension or pulseless electrical activity.

Abstract
The Health Insurance Portability and Accountability Act (HIPAA) is intended to simplify administrative processes and improve health information security. There are a number of traditional ways to address the expense and complexities of simplification, but none of them are bargains or beauties to behold: (1) Do-it-yourself encryption; (2) new back-end system purchases; (3) legacy system re-programming; or (4) onerous paper documentation. The good news is that 'second generation' e-health solutions are emerging that act as internal "wrappers" for health plan or provider data systems. They provide both an interface for end-users and a layer of security for organizational information and allow detailed patient-related data to remain at the system owner's physical location. These second generation solutions don't just 'connect,' data, they actually 'understand' the information, and can use data elements to invoke necessary rules, processing pathways, or personalization for specific stakeholders as required by HIPAA.
