Goal-setting to Promote a Healthier Lifestyle in Later Life: Qualitative Evaluation of the AgeWell Trial

Objective: We report a mixed method evaluation of the feasibility and implementation of the AgeWell goal-setting intervention to promote healthy ageing later life.

Method: Researcher field notes, goal-setting interview content, and semi-structured interviews with participants were content analysed to review trial implementation and participants’ perspective on the goal-setting and mentoring intervention.

Results: 75 people were recruited: 21 in the goal-setting and 22 in the goal-setting with mentoring arms of the intervention. Goal-setting was feasible in the main domains of interest. Adherence to the protocol was good and the mentoring schedule was adhered to. Participants reported satisfaction with their goal attainment, but barriers for non-achievement were also identified. Recommendations for small changes to the intervention included reducing the number of goals.

Conclusions: Participants understood the goal-setting process, and were able to set realistic and achievable lifestyle goals. The intervention and the procedures were acceptable but changes in how goal-setting is both introduced and monitored are needed for wider implementation.

Clinical Implications: Goal-setting can be a useful process to help people alter their lifestyle to allow them to age more successfully and reduce risk factors associated with dementia.     

Administration of low doses of MK-801 during ethanol withdrawal in the developing rat pup attenuates alcohol's teratogenic effects

BACKGROUND: Alcohol exposure during development can produce severe and long-lasting central nervous system damage and consequent behavioral alterations. Recent evidence suggests that NMDA receptor-mediated excitotoxicity during periods of withdrawal may contribute to this damage. We have demonstrated that blocking the NMDA receptor with MK-801 during alcohol withdrawal can attenuate ethanol's adverse effects on behavioral development in the rat. This study examined the dose dependency of MK-801's ability to mitigate ethanol's teratogenic effects. METHODS: Neonatal rat pups were exposed to 6.0 g/kg of ethanol in a binge-like manner on postnatal day (PD) 6, a period of brain development equivalent to a portion of the human third trimester. Alcohol administration was accomplished with an artificial rearing procedure. Twenty-one hours after ethanol treatment, pups were injected intraperitoneally with one of four doses of MK-801 (0.05, 0.1, 0.5, or 1.0 mg/kg) or saline vehicle. An artificially reared control and a normally reared control group were included. On PD 18-19, activity level was monitored, and on PD 40-42, serial spatial discrimination reversal learning was assessed. RESULTS: Alcohol exposure on PD 6 produced significant increases in activity level and deficits in reversal learning. These alcohol-induced behavioral alterations were significantly attenuated in subjects treated with one of the three lower doses (0.05-0.5 mg/kg) of MK-801 during withdrawal. The performance of ethanol-exposed subjects treated with the high dose of MK-801 (1.0 mg/kg) did not differ from that of the Ethanol Only group. CONCLUSIONS: These data suggest that alterations in NMDA receptor activation during alcohol withdrawal contribute to the neuropathology and consequent behavioral alterations associated with developmental alcohol exposure. These data have important implications for pregnant women and newborns undergoing ethanol withdrawal.     

Association of the ADH2 genotypes with skin responses after ethanol exposure in Japanese male university students

BACKGROUND: A contribution of the alcohol dehydrogenase-2 (ADH2) polymorphism to alcohol sensitivity and alcohol drinking behavior is still controversial. In this study, we examined the effects of the ADH2 genotypes on skin reactions to ethanol and habitual alcohol intake among Japanese male university students, controlling for the effects of the low Km aldehyde dehydrogenase (ALDH2) genotype, as an extension of our previous study. METHODS: The study subjects were 357 Japanese male students [average age (mean +/- SD) was 23.7 +/- 3.0 years] in a medical university. The subjects completed a questionnaire regarding self-reported alcohol-associated symptoms and alcohol-drinking behavior. The ADH2 and ALDH2 genotypes were determined through digestion of polymerase chain reaction products by restriction enzymes. All subjects participated in the ethanol patch test. We observed skin responses at 0, 5, 15, and 20 min after removal of the tape. RESULTS: Among the ALDH2*1/*1 genotypes, only some subjects with ADH2*1/*2 or ADH2*2/*2 exhibited a positive response, which increased with increasing time after the removal. However, none of comparisons between the different ADH2 genotypes reached statistical significance. Among the ALDH2*1/*2 genotypes, those with ADH2*1/*2 or ADH2*2/*2 showed a significant increase in response with increasing time after the removal and revealed a significantly higher positivity rate at 15 min than those with ADH2*1/*1. In those with the ALDH2*1/*2 genotype, the positive rate of facial flushing with one glass of beer was higher in those with ADH2*1/*2 and ADH2*2/*2 than those with ADH2*1/*1, although this was not significant. However, the ADH2 genotype did not seem to influence drinking frequency or amounts of alcohol intake in each ALDH2 genotype. CONCLUSIONS: This study finds further evidence for a contribution of the ADH2 polymorphism to skin reactions after either local or systemic ethanol exposure in Asian people. However, the effects of the ADH2 polymorphism may be mild because this polymorphism does not seem to influence alcohol drinking behavior in these study subjects.     

A Path Analysis of Latino Parental,Teenager and Cultural Variables in Teenagers' Sexual Attitudes,Norms, Self-Efficacy,and Sexual Intentions

OBJECTIVE:

to test a theoretical model based on the Parent-Based Expansion of the Theory of Planned Behavior examining relation between selected parental, teenager and cultural variables and Latino teenagers'' intentions to engage in sexual behavior.

METHOD:

a cross-sectional correlational design based on a secondary data analysis of 130 Latino parent and teenager dyads.

RESULTS:

regression and path analysis procedures were used to test seven hypotheses and the results demonstrated partial support for the model. Parent familism and knowledge about sex were significantly associated with parents'' attitudes toward sexual communication with their teenagers. Parent Latino acculturation was negatively associated with parents'' self-efficacy toward sexual communication with their teenagers and positevely associated with parents'' subjective norms toward sexual communication with their teenagers. Teenager knowledge about sex was significantly associated with higher levels of teenagers'' attitudes and subjective norms about sexual communication with parents. Only the predictor of teenagers'' attitudes toward having sex in the next 3 months was significantly associated with teenagers'' intentions to have sex in the next 3 months.

CONCLUSION:

the results of this study provide important information to guide future research that can inform development of interventions to prevent risky teenager sexual behavior among Latinos.

Development and initial evaluation of an instrument to assess physiotherapists’ clinical reasoning focused on clients’ behavior change

Background and Aim: A systematically developed and evaluated instrument is needed to support investigations of physiotherapists’ clinical reasoning integrated with the process of clients’ behavior change. This study’s aim was to develop an instrument to assess physiotherapy students’ and physiotherapists’ clinical reasoning focused on clients’ activity-related behavior and behavior change, and initiate its evaluation, including feasibility and content validity. Methods: The study was conducted in three phases: 1) determination of instrument structure and item generation, based on a model, guidelines for assessing clinical reasoning, and existing measures; 2) cognitive interviews with five physiotherapy students to evaluate item understanding and feasibility; and 3) a Delphi process with 18 experts to evaluate content relevance. Results: Phase 1 resulted in an instrument with four domains: Physiotherapist; Input from client; Functional behavioral analysis; and Strategies for behavior change. The instrument consists of case scenarios followed by items in which key features are identified, prioritized, or interpreted. Phase 2 resulted in revisions of problems and approval of feasibility. Phase 3 demonstrated high level of consensus regarding the instrument’s content relevance. Conclusions: This feasible and content-validated instrument shows potential for use in investigations of physiotherapy students’ and physiotherapists’ clinical reasoning, however continued development and testing are needed.

Central administration of corticotropin-releasing hormone alters downstream movement in an artificial stream in juvenile chinook salmon (Oncorhynchus tshawytscha)

We evaluated the effect of corticotropin-releasing hormone (CRH) on spatial distribution and downstream movement in an artificial stream in juvenile Chinook salmon (Oncorhynchus tshawytscha) during the period when the fish were able to tolerate seawater. An intracerebroventricular (ICV) injection of CRH (500 ng) to hatchery fish significantly increased the proportion of fish that were distributed downstream of a mid-stream release site. A second group of hatchery fish were given ICV injections of saline (control) or CRH (500 ng) and released near the top of the stream. The time taken to enter a trap at the lower end of the stream was recorded. In all cases the groups given CRH had a higher proportion of fish that did not enter the trap within 60 min of release. However, in those fish that did enter the trap, treatment with CRH increased the speed of downstream movement to this point relative to control fish. Wild sub-yearling Chinook salmon were captured during their downstream migration to the estuary and given ICV injections of saline or CRH (500 ng) either 2, 3, or 7 days after transport from the river. As with hatchery fish, a significantly higher proportion of wild fish that were administered CRH did not enter the trap at the lower end of the stream. The mean time of passage for control fish decreased on each successive day (day 2 > day 3 > day 7). In contrast, the mean passage time of the wild fish that were given CRH was relatively constant through time, and was only significantly faster than control fish on day 2. The current study provides evidence that CRH alters the downstream movement of juvenile Chinook in a simulated stream environment, and produces behavioral effects similar to those of juvenile salmonids that are stressed during their downstream migration.     

Relevance of Both Daily Hassles and the ALDH2 Genotype to Problem Drinking among Japanese Male Workers

The effects of genetic polymorphisms in the ALDH2 and ADH2 genes and stress levels, as assessed by the daily hassles scale on the prevalence of problem drinkers, were investigated in males in a Japanese occupational population. The frequency of problem drinkers was estimated by the Kurihama Alcoholism Screening Test (KAST). The prevalence of those with a high KAST score (≥0.0) was significantly higher in ALDH2*1/*1 (18.4%) than in ALDH2*1/*2 (4.8%). Multiple logistic regression analysis revealed significant contributions by levels of alcohol consumption, the ALDH2 genotype, and daily hassles to the prevalence of those with a high KAST score. When we analyzed the data for each ALDH2 genotype, heavier alcohol consumption (≥28.8 ml/day), older age (≥40 years old), and very high daily hassles levels (≥20) significantly increased the prevalence of problem drinkers in ALDH2*1/*1. On the contrary, no variables other than heavier alcohol consumption influenced the prevalence in ALDH2*1/*2. In summary, the present study revealed significant contributions of both daily hassles and the ALDH2 genotype to the increase of problem drinkers in an occupational population. Health promotion activities to prevent from alcohol dependence should focus on ALDH2*1/*1 , especially those of middle age, and should include stress management as a part of their activities.
