PREDICTIVE VARIABLES FOR WEIGHT CHANGE 2 YEARS FOLLOWING PARTICIPATION IN A WEIGHT LOSS INTERVENTION PROGRAM

A historical prospective study was designed to assess the man weight status of subjects who participated in a behavioral weight reduction program in 1983 and to determine whether there was an association between the dependent variable weight change and any of 31 independent variables after a 2 year follow-up period. Data was obtained by abstracting the subjects records and from a follow-up questionnaire administered 2 years following program participation. Five hundred nine subjects (386 females and 123 males) of 1460 subjects who participated in the program, completed and returned the questionnaire. Results showed that mean weight was significantly different (p < 0.001) between the measurement at baseline and after a 2 year follow-up period. The mean weight loss of the group was 5.8 pounds, 10.7 pounds for males and 4.2 pounds for females after a 2 year follow-up period. A total of 63.9% of the group, 69.9% of males and 61.9% of females were still below their initial weight after the 2 year follow-up period. Sixteen of the 31 variables assessed utilizing bivariate analyses were found to be significantly (p (LESSTHEQ) 0.05) associated with weight change after a 2 year follow-up period. These variables were then entered into a multivariate linear regression model. A total of 37.9% of the variance of the dependent variable, weight change, was accounted for by all 16 variables. Eight of these variables were found to be significantly (p (LESSTHEQ) 0.05) predictive of weight change in the stepwise multivariate process accounting for 37.1% of the variance. These variables included: Two baseline variables (percent over ideal body weight at enrollment and occupation) and six follow-up variables (feeling in control of eating habits, percent of body weight lost during treatment, frequency of weight measurement, physical activity, eating in response to emotions, and number of pounds of weight gain needed to resume a diet). It was concluded that a greater amount of emphasis should be placed on the six follow-up variables by clinicians involved in the treatment of obesity, and by the subjects themselves to enhance their chances of success at long-term weight loss. ^

Efficacy of a dilemma-focused intervention for unipolar depression: study protocol for a multicenter randomized controlled trial

BACKGROUND: Depression is one of the more severe and serious health problems because of its morbidity, disabling effects and for its societal and economic burden. Despite the variety of existing pharmacological and psychological treatments, most of the cases evolve with only partial remission, relapse and recurrence.Cognitive models have contributed significantly to the understanding of unipolar depression and its psychological treatment. However, success is only partial and many authors affirm the need to improve those models and also the treatment programs derived from them. One of the issues that requires further elaboration is the difficulty these patients experience in responding to treatment and in maintaining therapeutic gains across time without relapse or recurrence. Our research group has been working on the notion of cognitive conflict viewed as personal dilemmas according to personal construct theory. We use a novel method for identifying those conflicts using the repertory grid technique (RGT). Preliminary results with depressive patients show that about 90% of them have one or more of those conflicts. This fact might explain the blockage and the difficult progress of these patients, especially the more severe and/or chronic. These results justify the need for specific interventions focused on the resolution of these internal conflicts. This study aims to empirically test the hypothesis that an intervention focused on the dilemma(s) specifically detected for each patient will enhance the efficacy of cognitive behavioral therapy (CBT) for depression. DESIGN: A therapy manual for a dilemma-focused intervention will be tested using a randomized clinical trial by comparing the outcome of two treatment conditions: combined group CBT (eight, 2-hour weekly sessions) plus individual dilemma-focused therapy (eight, 1-hour weekly sessions) and CBT alone (eight, 2-hour group weekly sessions plus eight, 1-hour individual weekly sessions). METHOD: Participants are patients aged over 18 years meeting diagnostic criteria for major depressive disorder or dysthymic disorder, with a score of 19 or above on the Beck depression inventory, second edition (BDI-II) and presenting at least one cognitive conflict (implicative dilemma or dilemmatic construct) as assessed using the RGT. The BDI-II is the primary outcome measure, collected at baseline, at the end of therapy, and at 3- and 12-month follow-up; other secondary measures are also used. DISCUSSION: We expect that adding a dilemma-focused intervention to CBT will increase the efficacy of one of the more prestigious therapies for depression, thus resulting in a significant contribution to the psychological treatment of depression.

Screening for complex healing processes and psychological intervention in injured individuals

Introduction Injured individuals face a high risk for the development of psychological symptoms such as depression or anxiety, which influences early return to work after an accident. So far, it is unclear to which extent early psychological interventions can improve the ability to return to work. Purpose of the study The aim of the study was to investigate whether an improvement of the treatment-triage (by the screening questionnaire work and health [FAB]) influences early return to work and well being in injured individuals. Methods The study sample consists of injured individuals with different mental health-related or work-related disabilities after an accident. Participants are included eight weeks after an accident. Participants are randomly assigned to the intervention or to the control group. The intervention is an individualized psychotherapy consisting of cognitive-behavioral therapy and work related topics in an individual setting. Well being and work related actors are assessed at baseline and after six months. Results The recruitment is still ongoing. The preliminary results of this randomized controlled study will be presented at the conference. Conclusion An individualized psychotherapy might have the potential to improve the rehabilitation process in injured individuals and improve the ability to return to work.

Effects of a Transdiagnostic Internet Intervention («velibra») for Anxiety Disorders in Primary Care: Results of a Randomized Controlled Trial

Internet-based cognitive behavioral self-help treatment (ICBT) for anxiety disorders has shown promising results in several trials, but there is yet a lack of studies of ICBT in „real world” primary care settings. In this randomized controlled trial we recruited participants through general practitioners. The aim of the study was to examine whether treatment-as-usual (TAU) in primary care settings plus ICBT is superior to TAU alone in reducing anxiety symptoms and other outcome measures among individuals meeting diagnostic criteria of a least one of three anxiety disorders (social anxiety disorder, panic disorder with or without agoraphobia, generalized anxiety disorder). 150 adults fulfilling diagnostic criteria for a least one of the anxiety disorders according to a diagnostic interview are randomly assigned to one of the two conditions: TAU plus ICBT versus TAU. Randomization is stratified by primary disorder, medication (yes/no) and concurrent psychotherapy. ICBT consists of a transdiagnostic and tailored Internet-based self-help program for several anxiety disorders which also includes cognitive bias modification for interpretation (CBM-I). Primary outcomes are symptoms of disorder-specific anxiety measures and diagnostic status after the intervention (9 weeks). Secondary outcomes include primary outcomes at 3-month follow-up and secondary measures such as general symptomatology, depression, quality of life, adherence to ICBT and satisfaction with ICBT. The study is currently being completed. Primary results along with results for specific subgroups (e.g. primary diagnosis, concurrent medication and/or psychotherapy) will be presented and discussed.

Preventive Intervention as Means of Clarifying Direction of Effects in Socialization: Anxious-Withdrawn Preschoolers Case

An indicated preventive intervention research program integrating attachment, attributional, and behaviorist perspectives was conducted to test the hypothesis that parent-child relationship disturbances directly effect the child's adjustment to the preschool. Anxious-withdrawn preschool children and their mothers were divided equally into treatment and control groups, and assessed on maternal self-report of parenting stress, behavioral ratings of mother-child interaction, and teacher ratings of the children in the preschool classroom. Results showed significant changes in the treatment group: mothers in the treatment group moderated their level of control to a more appropriate, less intrusive level, while children in the treatment group showed an increase in cooperation and enthusiasm during a problem solving task with mother. Teacher-rated social competence and anxious-withdrawn behavior indicated improvement, although only the former was significant. The demonstration of effects of this home intervention for the mother on the child's behavior in the preschool confirm the transactional model underlying this study and demonstrate the utility of a parent-child interaction training component for the prevention of behavioral-emotional problems in young children.

The Effects of a Physical Activity Intervention on the way Elementary School Girls Play

The rates of childhood and adolescent obesity in the United States have been increasing steadily. American youth continue to eat more (increase energy intake) and reduce physical activity (decrease energy expenditure) resulting in increased body weight and body fatness. One way to help reduce body weight in children is to increase physical activity. The purpose of this study was to determine if an age appropriate before-school physical activity intervention would be successful in increasing energy expenditure, intensity of activity, and behavioral approaches in overweight girls. The subjects were recruited from Parker Memorial School in Tolland, Connecticut, and two testing periods occurred over an eight week period. Video recordings of each physical activity session were analyzed to determine energy expenditure, exercise intensity, and behaviors during exercise. Data was evaluated for normal distribution, and paired t-tests were used to determine statistical significance. This study showed that the age appropriate before school physical activity intervention was able to increase energy expenditure and exercise intensity and have a positive effect on behavioral approaches in overweight girls.

Environmental and behavioral risk factors for moderate or severe rotavirus diarrhea in children less than 24 months

On a global basis rotaviruses are the most important agents involved in childhood diarrhea. In developing countries they account for 6% of all diarrheas and 20% of all diarrhea related deaths of children under 5 years of age, with over 1 billion episodes and over 4 million deaths annually. Given the disease burden, there is a need for better understanding the risk factors involved in rotavirus disease, to identify areas of intervention. In order to provide this information, two areas were developed: a review of the literature, examining the causal evidence for rotavirus diarrhea and a case comparison study. The case comparison study analyzed two areas: identifying climate factors and, identifying environmental and behavioral risk factors. The literature review showed that few analytical studies have identified specific risk factors such as home environment, and a winter seasonal trend for temperate areas, but in key areas evidence is contradictory. The case comparison study for climate factors demonstrated that seasonality occurs in a tropical country like Venezuela and that a complex interplay between weather conditions contribute to the seasonal pattern. A positive association between rain fall (OR 4.1); dew point (OR 2.3) and temperature differential during the day (OR 1.4) and, an inverse association with temperature (OR 0.5) and relative humidity (OR 0.8) was found. This information is useful in understanding the seasonal pattern of rotavirus and for planning health care needs. The second analysis demonstrated that environmental variables such as crowding (OR 14.3), contact with someone with an infectious disease (OR 4.9) and animal ownership (OR 2.3) were important. Restricting the analysis to animal owners demonstrated that living In a rural settling (OR 13.8), defecating in inappropriate places (OR 7.2), crowding(4.2) and indoor animals (4.0) are of importance. Behavioral variables identified were: lack of breast feeding (OR 4.0) and visiting when someone was sick (OR 3.4). Biological and demographic variables of importance were: age, with a dose response relationship; undernurishment (OR 11.3) and household per capita monthly income less than US $ 16.30 (OR 8.5). Using a diarrhea compeer group we found that, although some of the previous variables were of importance, no major differences were found. These findings are important in identifying paths for prevention and further research. ^

Determining acquisition and cessation antecedents to adolescent cigarette smoking for development of intervention strategies

Our national focus and emphasis on the promotion of healthy behavior choices regarding tobacco and other drugs continues to target adolescents. Multiple studies have shown that adolescence is the optimum period for the prevention of substance use initiation as life-long patterns of health behaviors are established during this critical developmental stage. Tobacco use is associated with an increase in morbid and mortal health conditions of which prevalence increases throughout the lifespan. Attention to the antecedents of preventable health conditions aims to modify the risks and identify health promotion factors. Modifying antecedent factors for tobacco initiation in youth and identifying protective factors for successful smoking cessation has major public health implications across the lifespan. Of foremost interest are those risk factors and resultant behaviors that predict a youth's probability of initiating cigarette use and their cessation of cigarette use. Specifically, this dissertation supports previous results identifying intervention variables on the initiation/cessation continuum model especially with the established predictors of smoking (decisional balance and susceptibility) and with more recently identified predictors of smoking (nicotine dependence and withdrawal symptoms) in current and former smokers in a sample of high school students in Austin and Houston, Texas. These results offer insight for the development of appropriate intervention program strategies for our youth. ^

Social and behavioral determinants of consistent condom use among female commercial sex workers (FCSWs) in Ghana

This study aims at investigating the social and behavioral predictors of consistent condom use among female commercial sex workers (FCSWs) in Ghana. Street commercial sex workers were interviewed in Accra, Kumasi and Techiman. Whereas respondents had attained certain accurate knowledge about HIV transmission routes, misconceptions were still commonly reported. The level of condom education was very low (14%), however consistent condom use (all the time) with clients was relatively high (49.6%), 38.89% reported using condom sometimes and 11.56% reported never using condoms. ^ 277 of the respondent ants did not use condoms all the time. 163 of them reported not using condoms due to refusal by their clients, the remaining 64 respondents did not even request their clients to use condom due to cultural perception of power, lack of authority and the fear of loosing clients. ^ Significant predictive factors associated with consistency of condom use among FCSWs in a multivariate analysis were; age, level of education, religion, and number of customers. Some of the major obstacles to condom use by the FCSWs were refusal by clients, availability of free condoms, trying to communicate trust to their clients, and the lack of empowerment to negotiate safer sex with clients. Some of the respondents may have developed a false sense of safety by subjectively assessing whether their clients were well and do not look sick, but they were unaware that HIV carriers may show no obvious symptoms of illness at all. ^ In summary, this study points to an urgent need for reestablishing effective prevention intervention and some insights of what is required of such program in Ghana. ^

A formative evaluation of the American Diabetes Association's Choosing Health and Sensible Exercise childhood obesity intervention

Background. The increasing prevalence of overweight among youth in the United States, and the parallel rise in related medical comorbidities has led to a growing need for efficient weight-management interventions. Purpose. The aim of this study was to evaluate the effects of the Choosing Health and Sensible Exercise (C.H.A.S.E.) childhood obesity prevention program on Body Mass Index (BMI), physical activity and dietary behaviors. Methods. This study utilized de-identified data collected during the fall 2006 session of the C.H.A.S.E. program. A total of 65 students at Woodview Elementary School and Deepwater Elementary School participated in this intervention. The C.H.A.S.E. program is a 10-week obesity prevention program that focuses on nutrition and physical activity education. Collection of height and weight data, and a health behavior survey was conducted during the first and last week of the intervention. Paired t-tests were used to determine statistically significant differences between pre- and post-intervention measurements. One-way analysis of variance was used to adjust for potential confounders, such as gender, age, BMI category ("normal weight", "at risk overweight", or "overweight"), and self-reported weight loss goals. Data were analyzed using STATA, v. 9.2. Results. A significant decrease in mean BMI (p< 0.05) was found after the 10-week intervention. While the results were statistically significant for the group as a whole, changes in BMI were not significant when stratified by age, sex, or ethnicity. The mean overall scores for the behavior survey did not change significantly pre- and post-intervention; however, significant differences were found in the dietary intention scale, indicating that students were more likely to intend to make healthier food choices (p<0.05). No statistically significant decreases in BMI were found when stratified for baseline BMI-for-age percentiles or baseline weight loss efforts (p>0.05). Conclusion. The results of this evaluation provide information that will be useful in planning and implementing an effective childhood obesity intervention in the future. Changes in the self-reported dietary intentions and BMI show that the C.H.A.S.E. program is capable of modifying food choice selection and decreasing BMI. Results from the behavior questionnaire indicate that students in the intervention program were making changes in a positive direction. Future implementation of the C.H.A.S.E. program, as well as other childhood obesity interventions, may want to consider incorporating additional strategies to increase knowledge and other behavioral constructs associated with decreased BMI. In addition, obesity prevention programs may want to increase parental involvement and increase the dose or intensity of the intervention. ^

An intervention mapping approach: Identification of human trafficking victims by health professionals

Background. Today modern day slavery is known as human trafficking and is a growing pandemic that is a grave human rights violation. Estimates suggest that 12.3 million people are working under conditions of force, fraud or coercion. Working toward eradication is a worthy effort; it would free millions of humans from slavery, mostly women and children, as well as uphold basic human rights. One tactic to eradicating human trafficking is to increase identification of victims among those likely to encounter victims of human trafficking.^ Purpose. This study aims to develop an intervention that improves certain stakeholders' ability, in the health clinic setting, to appropriately identify and report victims of human trafficking to the National Human Trafficking Resource Center.^ Methods. The Intervention Mapping (IM) process was used by program planners to develop an intervention for health professionals. This methodology is a six step process that guides program planners to develop an intervention. Each step builds on the others through the execution of a needs assessment, and the development of matrices based on performance objectives and determinants of the targeted health behavior. The end product results in an ecological, theoretical, and evidence based intervention.^ Discussion. The IM process served as a useful protocol for program planners to take an ecological approach as well as incorporate theory and evidence into the intervention. Consultation with key informants, the planning group, adopters, implementers, and individuals responsible for institutionalization also contributed to the practicality and feasibility of the intervention. Program planners believe that this intervention fully meets recommendations set forth in the literature.^ Conclusions. The intervention mapping methodology enabled program planners to develop an intervention that is appropriate and acceptable to the implementer and the recipients.^

A promotora de salud CVD intervention: Participant responses after Su Corazon, Su Vida education

In this study we sought to identify and understand feelings, benefits and barriers to making heart healthy behavioral changes by reviewing and analyzing participant responses to a follow-up telephone survey conducted as part of the HEART project (Health Education Awareness Research Team). Individuals who participated in HEART attended classes and received “Su Corazon, Su Vida” education. The HEART follow-up telephone survey was conducted only on those participants who were part of the experimental group. A total of 93 individuals from this group were successfully contacted for participation in the telephone survey after the classes ended. Quantitative data regarding ‘feelings’ and ‘difficulty making heart healthy behavioral changes’ were analyzed by calculating frequencies of each category of response for post-intervention weeks 9, 13, and 15. In addition, Wilcoxon rank-sum tests were conducted for post-intervention at weeks 9, 13, and 15 to measure associations between feelings and difficulties making heart healthy behavioral changes. Changes in responses over time for feelings and difficulties making heart healthy behavioral changes were looked at by counting differences in responses between pairs of follow up weeks. Qualitative responses to the survey were analyzed by categorizing content of responses under themes in order to identify factors related to feelings and difficulties making heart healthy behavioral changes. Telephone survey participants showed positive attitudes towards making nutritional and physical activity changes. Out of the 93 telephone survey respondents, 53 (57%) reported some type of physical activity change during the follow-up period while 46 (49%) reported specific changes in nutrition. Data from the “difficulty to making changes” responses were categorized under constructs from the Health Belief Model, perceived benefits and barriers. Overall, the barriers for physical activity were health issues, individual habits and time. Barriers to eating healthy were family support, individual habits, and knowledge. This study suggests that with respect to nutritional knowledge barriers, educational programs should explore other ways of teaching and familiarizing individuals with information sources that may be more appropriate for those populations not accustomed to them. For example, nutrition labels, portions, recipes, and use of photonovelas. Our findings of the barriers to changes in food preparation due to lack of family support may also suggest the need for the development of programs where influential partners or relatives are involved in order to create a more supportive environment which may provide more opportunity for change toward healthier lifestyle behaviors. Finally, the physical activity barriers found suggest that it may be beneficial to recommend appropriate exercises for those with specific health problems or those with time restrictions due to work or travel so that physical activity is not completely avoided.^

Behavioral journalism newsletters to increase employee participation in a free worksite wellness center

Background. Providing an worksite fitness center for employees is an effective setting to increase an adult’s levels of physical activity, demonstrably reducing health care costs and elevating employee productivity. Increasing compliance and adherence among employees to consistently utilize an onsite facility remains a challenge.^ Purpose. To illustrate if two electronic behavioral journalism newsletters can increase employee participation in a free worksite wellness center.^ Design. A randomized control trial was implemented. ^ Setting. A large petroleum-producing corporation located in Houston, Texas Subjects.70 full or part time employees that had checked into visited the wellness center during September, October, and November 2009. ^ Intervention. Two behavioral journalism newsletters were created based on authentic community member role model interviews. Newsletters were distributed to intervention group participants via company email. Intervention and control group participant’s visits to the wellness center were monitored via a key card check in system at the facility for two weeks following the newsletter intervention.^ Analysis. Count variable statistics were used to identify rate differences between the intervention and control group wellness center visits. A binomial test for equality of proportions was used to identify differences between participants that had at least one visit to the wellness center compared with those with none.^ Results. Both intervention and control groups had a baseline of zero wellness center visits. The control group had a mean visit rate 0.441 and the intervention group had 0.857. A 0.416, almost one half more visits were found among the intervention group.^ Conclusion. This study indicates that behavioral journalism newsletters featuring a role model from within the worksite population can be a cost effective communication method to improve participation in an onsite wellness center. ^

A COMPARISON OF COUNTY HOSPITAL UTILIZATION BEFORE AND AFTER INTERVENTION BY THE HOSPITAL'S ALCOHOLISM SERVICES PROGRAM

This study examines the reduction in hospital utilization of 393 public hospital patients who were referred to the hospital's alcoholism screening program for intervention. The 393 patients were the total patient population of the alcoholism screening program for the period of September through December, 1982. Medical records of these patients were investigated to assess the total number of hospital days six months before and six months after intervention. The findings support the hypothesis of decreased utilization. The total number of hospital days for 393 patients before intervention of the alcoholism program was 3,458, with a mean length of stay of 8.80 days. The total number of hospital days after intervention was 458 days, with a mean length of stay of 6.50 days. The average individual difference (decrease) was 7.63 days for one year. From a total of 393 patients counseled by the alcoholism program, 106 (27%) went to treatment for their alcoholism. Other aims were to examine the referral sources (physicians, nurses, social workers and the MAST); study the impact of familial history of alcoholism on referrals, and explore the MAST scores of patients successfully referred. Implications of the study are that it would benefit the public hospital, with their disproportionate numbers of alcoholics, to intervene in the behavioral patterns of alcoholism. Such intervention would be a factor in reducing the overall hospitalization of the alcoholic. ^
