does gender health disparity begin in adolescence?

ISMH Congress 2010 Abstracts Conclusion: The number of new clients of Klaip ˙ eda ACC and the number of their visits to ACC was constantly growing throughout 1997-2006. The number of disinfection and contraception means, handed out to the ACC clients, was increasing during 1997-2006 subject to the increasing number of ACC clients. Consultations of social workers, preventive information, training and consultation about the possibilities for treatment from the drug addiction were most often held for IDU. The service of mediation and directing of clients to other institutions and distribution of editions about safe sexual relations were carried out at least. The activity of ACC encouraged positive changes of IDU behaviour — it became safer both in the field of drug use and in the field of sexual relations. The more frequently IDU visit ACC, the more real possibility of stopping drug use they see. doi:10.1016/j.jomh.2010.09.203 ISMH World Congress 2010 Abstract 203 DOES GENDER HEALTH DISPARITY BEGIN IN ADOLESCENCE? S. Ghannam, S. Shabsigh, D. Hajo, J. Jhaveri, R. Shabsigh Maimonides Medical Center, Brooklyn, USA E-mail address: [email protected] (R. Shabsigh). Background: Contributing to the health disparity between adult men and women are health risk behaviors. Although potentially modifiable, a first step requires us to ask, when do these behavioral differences begin? Methods: Using data from the 2009 Youth Risk Behavior Surveillance Study we examined responses of 16,000+ American teenagers. Answers to a vari- ety of health risk behavior questions were analyzed for differences in prevalence between genders. Results: Compared to girls, boys were more likely to drive while drink- ing alcohol (11.6% n = 7,890 vs. 7.6% n = 8.173 p < 0.001), carry a weapon (27.1% n = 7,848 vs. 7.1% n = 8,203 p < 0.001), and engage in fighting (39.1% n = 7,890 vs. 22.9% n = 8,183 p < 0.001). Compared to girls, prevalence of recent tobacco use (29.8% n = 7,301 vs. 21.8% n = 7,641 p < 0.001) and “heavy” smoking (11.1% n = 1,570 vs. 4.1% n = 1,354 p < 0.001) was more common in boys. Compared to girls, boys were more likely to experiment with drugs: marijuana (39.0% n = 7,849 vs. 34.3% n = 8,148 p < 0.001), cocaine (7.3% n = 7,927 vs. 5.3% n = 8,214 p < 0.001), heroin (3.2% n = 7,750 vs. 1.7% n = 7,923 p < 0.001), ecstasy (7.6% n = 7,811 vs. 5.5% n = 8,016 p < 0.001), methamphetamine (4.7% n = 7,982 vs. 3.3% n = 8,244 p < 0.001), other intravenous drugs (2.7% n = 7,923 vs. 1.4% n = 8,157 p < 0.001). Compared to girls, boys were more likely to have multiple sexual partners (16.2% n = 7,261 vs. 11.2% n = 7,672 p < 0.001) and have sex while using drugs or alcohol (25.9% n = 2,692 vs. 17.1% n = 2,829 p < 0.001). 76% of boys did not eat five servings of fruits and vegetables daily (n = 7,851). Over half of all boys did not have regular physical activity (54.4% n = 7,881). Prevalence of obesity was higher in boys than girls (15.3% n = 7,572 vs. 8.3% n = 7,606 p < 0.001). Conclusion: Regarding health behaviors among teenagers, boys demon- strated riskier behavior than girls. Injurious and violent behavior, tobacco and drug use, risky sexual practices and obesity were more prevalent in boys. Lifelong behavioral patterns are established in adolescence, possibly becoming risk factors for chronic disease later in adulthood. Identifying differences in teen behavior allows for targeted intervention, bringing us closer to improving future outcomes of men’s health. doi:10.1016/j.jomh.2010.09.204 ISMH World Congress 2010 Abstract 204 TESTOSTERONE AUGMENTS POLYPHENOL-INDUCED DNA DAM- AGE RESPONSE IN PROSTATE CANCER CELLS Hisamitsu Ide, Lu Yan, Yu Jingsong, Satoru Muto, Shigeo Horie Teikyo University School of Medicine, Tokyo, Japan E-mail address: [email protected] (S. Horie). Background: Recently, we reported that combined ingestion of soy isoflavones and curcumin significantly decreased serum level of prostate- specific antigen based on a randomized placebo-controlled double-blind clinical study. We investigated whether these polyphenols inhibited the proliferation of prostate cancer cells by activating a DNA damage response. Materials and Methods: The effects of isoflavones and curcumin on the expression and phosphorylation of ATM (ataxia-telangiectasia-mutated kinase), H2AX (histone H2AX variant), and Chk2 (checkpoint kinase2) were examined in LNCaP cells. The induction of apoptosis in LNCaP cells was evaluated by poly(ADP-ribose) polymerase (PARP) cleavage. Further- more, the effects of a testosterone supplement on modulation of the DNA damage response were examined. Results: Combined treatment of isoflavones and curcumin additively suppressed cellular proliferation and induced phosphorylation of ATM, histone H2AX, Chk2, and p53. Testosterone augmented the activation of the DNA damage response and PARP cleavage induced by curcumin. Conclusion: Our results indicate that the activation of the DNA damage response by the polyphenols might suppress the malignant transforma- tion of prostate cancer. In addition, testosterone, when combined with the polyphenols, may have suppressive effects on the progression of prostate cancer. doi:10.1016/j.jomh.2010.09.205 ISMH World Congress 2010 Abstract 205 THE [-2]PROPSA AND THE PROSTATE HEALTH INDEX (PHI) IMPROVE THE DETECTION OF PROSTATE CANCER FOR PATIENTS WITH TOTAL PSA BETWEEN 1.8 AND 8.0 NG/ML J-S Blanchet a,,1 , A.

Blanchet). Introduction: The benefit of screening for prostate cancer (PCa) using the prostate specific antigen (PSA) as a biochemical marker is currently the focus of intense debate because of inadequate clinical performance. Beck- man Coulter has recently developed a new approach with the Prostate Health Index (phi) 2 which combines the results of total PSA, free PSA and [-2]proPSA, a molecular isoform of free PSA. The clinical performance of this index for the detection of PCa is currently being evaluated in a multicenter study. Material and Methods: After six months of recruitment, 250 men (107 with and 143 without PCa) with total PSA levels between 1.8 - 8.0 ng/mL (WHO Calibration) and non-suspicious digital rectal examination (DRE) were included in the study. All PCa cases were confirmed by biopsies with 10 cores or more. The total serum PSA, free PSA and [-2]proPSA were mea- sured on a Beckman Coulter DxI800 automated immunoassay analyzer. Results: Unlike the total PSA and free PSA, serum levels of [-2]proPSA were significantly higher in the PCa group compared with the group without PCa. The parameters % free PSA, %[-2]proPSA and phi were significantly dif- ferent for the group of patients with PCa. A strong relationship between the percentage of positive biopsies and phi was confirmed. The diagnostic performance of the 4 parameters by ROC curve analysis showed a highly significant superiority for %[-2]proPSA (AUC: 0.72) and phi (AUC: 0.72) com- pared to total PSA (AUC: 0.53) and % free PSA (AUC: 0.58). If prostate biopsy indication would have been based on %fPSA value with a 25% cut off, 14 PCa would not have been detected. The phi index, with a cut of at 23, would have detected 12 of these 14 cancers. Conclusion: The results of this evaluation confirmed the clinical superiority of [-2]proPSA and phi for the detection of PCa in the concentration range of 1.8 - 8.0 ng/mL total PSA. The phi index improves the detection of PCa patients with %fPSA > 25%. doi:10.1016/j.jomh.2010.09.206 1 Not intended as off-label promotion of any Beckman Coulter prod- uct. 2 Not available in the United States. jmh Vol. 7, No. 3, pp. 282–351, October 2010 345
