The Relationship

Context: Previous studies have reported that the incidence of patellofemoral pain in women is 2.2 times higher than that in men. Lower hip frontal dynamic joint stiffness in women may be related to the magnitude of hip adduction and internal rotation associated with patellofemoral pain. Objective: To identify sex differences in hip frontal dynamic joint stiffness and examine the relationship between hip frontal dynamic joint stiffness and hip adduction and internal rotation during gait. Design: Cross-sectional study. Setting: University campus. Participants: A total of 80 healthy volunteers (40 women and 40 men) participated in this study. Intervention(s): Kinematic and kinetic data during gait were collected using a motion capture system and force plates. Main Outcome Measures: Hip frontal dynamic joint stiffness, hip adduction, and hip internal rotation were calculated during gait. Results: Women demonstrated lower hip frontal dynamic joint stiffness than men during gait (P < .01). They also displayed decreased hip frontal dynamic joint stiffness associated with increased hip adduction (r = −.85, P < .001) and internal rotation (r = −.48, P < .001). Conversely, in men, decreased hip frontal dynamic joint stiffness was associated with increased hip adduction (r = −.74, P < .001) but not internal rotation (r = .17, P = .28). Conclusions: Sex differences between hip frontal dynamic joint stiffness and hip internal rotation during gait may contribute to the increased incidence of patellofemoral pain in women.

Context: The repetitive demands of throwing affect glenohumeral (GH) range of motion (ROM) and strength. Less is known about hip alterations in skeletally immature athletes. Objective: To compare GH and hip ROM and strength between age, position, and side of youth baseball athletes. Design: Cross-sectional study. Setting: Multicenter testing. Patients or Other Participants: Seventy-two healthy baseball athletes. Participants' self-reported characteristics were age group (7−11 years [n = 28] or 12−18 years [n = 44]), position (pitcher [n = 22], position player [n = 47], unreported [n = 3]), and side (throwing or nonthrowing arm, lead or stance leg). Main Outcome Measure(s): Bilateral GH and hip internal- and external-rotation ROM were measured passively and summed for total arc of motion (TAM). Glenohumeral and hip rotation and gluteus medius strength were measured. Analyses included linear mixed models. Results: Glenohumeral internal rotation was less in throwing than in nonthrowing arms (P &lt; .05) except in younger pitchers (P = .86). Compared with older athletes, younger athletes had more GH external rotation (103.3° ± 7.7° versus 97.5° ± 9.4°; P = .002), TAM (156.4° ± 8.7° versus 147.9° ± 10.9°; P = .04), and external rotation in throwing compared with nonthrowing arms (101.9° ± 1.2° versus 97.9° ± 1.1°; P &lt; .001). Glenohumeral TAM was less in throwing than in nonthrowing arms (150.5° ± 2.1° versus 154.9° ± 1.3°; P = .01). Younger athletes had more hip internal rotation (38.9° ± 6.8° versus 31.2° ± 7.5°; P &lt; .001) and TAM (68.4° ± 10.0° versus 60.7° ± 9.8°; P = .001) than older athletes. Lead-leg hip internal-rotation ROM was greater than in the stance leg (34.8° ± 8.9° versus 32.8° ± 7.7°; P = .01). Overall, older players were stronger than younger players (P &lt; .05), and the throwing arm was stronger in internal rotation than the nonthrowing arm (10.12 ± 3.72 lb [4.59 ± 1.69 kg] versus 9.43 ± 3.18 lb [4.28 ± 1.44 kg]; P = .047). Conclusions: Youth baseball athletes had typical GH ROM adaptations of less internal rotation and more external rotation in the throwing versus the nonthrowing arm. Greater ROM in younger athletes may be explained by prepubertal characteristics. We obtained hip-strength values in youth baseball athletes, and as expected, older athletes were stronger.

Abstract Background: Limited research has explored sex differences in the relationship between partner behavior and attitudes and smoking cessation. Methods: The study examined sex partner attitudes about smoking among men and women who are currently trying to quit smoking cigarettes. Data were collected as part of the Tobacco Use in Drug Environment (TIDE) study, a cross-sectional study conducted in Baltimore, MD, USA from September 2013-May 2015. Interviews were administered with current smokers. The sample size for the current analysis was 134 men and 86 women. Results: Approximately thirty-three percent of male participants (n=45) reported currently trying to quit smoking cigarettes. Twenty-nine percent of women were currently trying to quit. Having a sex partner who did not mind the participant’s smoking was associated with decreased odds of trying to quit among men (AOR=0.35, p=0.03, 95% CI: 0.13, 0.91). Having a sex partner who expressed concern about the participant’s smoking (AOR=12.9, p<0.01, 95% CI: 3.49, 47.0) and having a sex partner who encouraged the participant to quit smoking was significantly associated current quit attempt. Conclusions: The relationship between partner support for cessation and current quit attempt was stronger for women than men in this population. Understanding sex-partner attitudes regarding smoking and their relationship to smoking cessation activities may provide insights for future tailored cessation interventions.

OBJECTIVE: to determine the prevalence of radiographic signs of femoroacetabular impingement (FAI) in asymptomatic adults and correlate them with data from physical examinations. METHODS: We conducted a cross-sectional study with 82 asymptomatic volunteers, 164 hips, between 40 and 60 years of age, selected by convenience. They were submitted to anamnesis and clinical examination of the hip, anteroposterior (AP) pelvis radiographs with three incidences, Dunn 45° and Lequesne false profile of each hip, to measure the variables. We measured the alpha angle, anterior offset of the femoral neck, cervical diaphyseal angle, CE angle of Wiberg, acetabular index, Sharp angle, and the crossing, ischial spine and posterior wall signs. RESULTS: our sample consisted of 66% women, mean age of 50.4 years. The average alpha angle was 45.10°, SD=8.6. One quarter of the hips showed alpha angle greater than or equal to 50°; among men the prevalence was 34%, and among women, 11%. We found indicative radiographic signs of femoroacetabular impingement in 42.6% of hips, whether femoral or acetabular, and the increased alpha angle was related to the decrease in hip internal rotation (p<0.001). CONCLUSION: the radiographic findings of femoroacetabular impingement in asymptomatic patients were frequent in the studied sample. The increase in alpha angle was associated with decreased internal rotation.

The Relationship

Background: Deliberate self-harm (DSH) occurs with high frequency among clinical and nonclinical youth populations. Although depression has been consistently linked with the behavior, not all depressed individuals engage in DSH. Aims: The current study examined maladaptive coping strategies (i.e., self-blame, distancing, and self-isolation) as mediators between depression and DSH among undergraduate students. Methods: 202 students from undergraduate psychology courses at a private university in Southern California (77.7% women) completed anonymous self-report measures. Results: A hierarchical regression model found no differences in DSH history across demographic variables. Among coping variables, self-isolation alone was significantly related to DSH. A full meditational model was supported: Depressive symptoms were significantly related to DSH, but adding self-isolation to the model rendered the relationship nonsignificant. Limitations: The cross-sectional study design prevents determination of whether a casual relation exists between self-isolation and DSH, and obscures the direction of that relationship. Conclusions: Results suggest targeting self-isolation as a means of DSH prevention and intervention among nonclinical, youth populations.

The well is one of the source water used for bathing, washing, and drinking by the citizens in Jiken Hamlet, Rarang Village, Terara Sub-District. Poor dug well construction conditions can affect the amount of coliform bacteria contained in the dug well water. The purpose of this study is to identify the construction of dug wells and the content of coliform bacteria in dug well water and determine the relationship between dug well construction and the content of coliform bacteria. This research is analytic with a cross sectional study design. The results were obtained from 11 samples of dug wells which were observed in construction and the coliform content was known that all samples did not requirements as good dug well construction. Coliform content test results showed that as many as 5 dug well water samples did not pass the clean water quality standards. The results of data analysis with the chi-square test variable construction of dug wells with coliform content variable  showed 0,172 > 0,05, then the concluded is the dug well not suitable to use by people in that area as a source of water for daily needs.
