BACKGROUND: Some individuals perceive themselves as being normal weight, despite having an excess body fat percentage (e.g., underestimate weight). Conversely, other individuals perceive themselves as being overweight, despite having a normal body fat percentage (e.g., overestimate weight). When perceived and actual we…

This cross-sectional study focused on the epidemiology of overweight and obesity and the association with demographic and socioeconomic variables in a sample of 794 Xukuru of Ororubá adults 19-59 years of age, from an indigenous reserve in Pesqueira County, Pernambuco State, Brazil. Descriptive analyses and multiv…

PURPOSE: The current study's purpose was to determine morphometric analysis of all facial foramina and mandibular angle relative to surgical landmarks from cone beam computed tomographic scans. MATERIALS AND METHODS: Three-dimensional computed tomographic scans were reconstructed from data of 100 patients (200 sides)…

OBJECTIVE: This study's aim is the assessment of language development of children with Cochlea Implant (CI). It focusses on receptive and expressive language development as well as auditory memory skills. MATERIAL AND METHODS: Grimm's language development test (SETK 3-5) evaluates receptive, expressive language develo…

BACKGROUND AND OBJECTIVES: This study investigated the effect of a couple-based cognitive behavioral therapy (CBT) for the treatment of obsessive-compulsive disorder (OCD) on the intimate partners of patients. Previous research has shown this intervention to be efficacious in reducing OCD symptoms and comorbidities in…

This study examined changes in the propulsive force and stroke parameters of arm-amputee and able-bodied swimmers during tethered swimming. Eighteen well-trained female swimmers (nine unilateral arm amputees and nine able-bodied) were videotaped performing maximal-effort 30 s front-crawl swims, while attached to a load…

PURPOSE: This study's purpose was to develop a task-specific self-efficacy scale for maternal oral care (SESMO) with reliability and validity. METHODS: A draft scale consisting of 36 items was designed and tested on 119 mothers at a dental clinic. Item analysis was performed to improve its accuracy by reducing the num…

The current study investigated the effects of alcohol and gender on the intentions of engaging in sexual risk-taking. Young adults (101 men, 99 women) were randomly assigned to the alcohol, placebo, or no-alcohol conditions. Participants listened to an audiotaped scenario that presented a romantic situation between a m…

Using an 'at-risk' sample of African American girls, the present study examined the link between girls' retrospective reports of pubertal timing, girls' perceived relative pubertal timing, and their behavioral and emotional problems as rated by the girls themselves (N=102; 11-17 years), as well as teachers and parents.…

In this study, I examined direct and indirect influences of sensation seeking, a personality trait, on adolescent drug use. I hypothesized that some or even most of the contribution of sensation seeking to drug use by adolescents is mediated through association with deviant peers and communication with peers that is fa…

A methodology for sampling homeless populations in inner Melbourne was developed to study their health status and prevalence of tuberculosis. This paper describes the design, development and implementation of the project. The results of health status and tuberculosis analysis are published elsewhere. Involvement and in…

Although many African countries have made significant progress towards universal access to water, energy, and food resources (WEF), assessing the ecological response to the increasing productivity of these resources is not well researched, which carries the risk of ecological deficit, resource degradation, and ineffici…

The alcohol dehydrogenase (ADHs) and aldehyde dehydrogenases (ALDHs) involved in alcohol metabolism are polymorphic. Different alleles encode subunits of the enzymes that are related to differences in alcohol metabolism with different ethnic groups. This study examined the allele frequencies at the ADH1, ADH2, ADH3 and…

This study addressed the question of how to structure coalitions in order to increase their engagement in multiple strategies for health promotion and consequently to improve their effectiveness. Three structural variables were chosen: (i) coalition's heterogeneity, captured by the professional diversity of its members…

The study's purpose was to assess whether individuals who developed a second malignant neoplasm (SMN) after treatment for a first malignant neoplasm (FMN) had a lower ability to repair DNA double-strand breaks (DSBs) using a bioassay with γH2AX intensity as a surrogate endpoint. In a case-control study nested in…

BACKGROUND: Several hip fracture clinical prediction models have been developed. We conducted this study to (i) map outcomes used in clinical prediction models for hip fracture, (ii) identify the domains and instruments of predictors, and (iii) assess the risk of bias. METHODS: We performed systematic searches of stud…
