Relationship between psychological and biological factors and physical activity and exercise behaviour in Filipino students

The aim of the present study was threefold. Firstly, it investigated whether a general measure or specific measure of motivational orientation was better in describing the relationship between motivation and exercise behaviour. Secondly, it examined the relationship between the four most popular indirect methods of body composition assessment and physical activity and exercise patterns. Thirdly, the interaction between motivation and body composition on physical activity and exercise behaviour was explored in a sample of 275 Filipino male and female students. Males were found to have higher levels of exercise whereas females had higher levels of physical activity. Furthermore, general self-motivation together with body weight and percentage body fat were found to be the best predictor of exercise behaviour whereas the tension/pressure subscale of the ‘Intrinsic Motivation Inventory’ (IMI) was the best predictor of levels of physical activity. However, significant gender differences were observed. That is, for the males only self-motivation and for the females only body weight and BMI predicted exercise behaviour. Also, tension/pressure predicted physical activity levels for the females but not the males. No inverse relationship was found between the four body composition measures and exercise and physical activity behaviour. The results support the notion that the psychobiological approach might be particularly relevant for high intensity exercise situations but also highlights some important gender differences. Finally, the results of this study emphasise the need for more cross-cultural research

Improving Prevention of Mother-to-Child Transmission of HIV Care and Related Services in Eastern Rwanda

Younsook Lim and colleagues describe the Rwanda Learning Collaborative on Child Health, which aimed to improve and extend the impact of prevention of mother-to-child transmission of HIV/AIDS

Can a quality improvement project impact maternal and child health outcomes at scale in northern Ghana?

Background Quality improvement (QI) interventions are becoming more common in low- and middle-income countries, yet few studies have presented impact evaluations of these approaches. In this paper, we present an impact evaluation of a scale-up phase of ‘Project Fives Alive!’, a QI intervention in Ghana that aims to improve maternal and child health outcomes. ‘Project Fives Alive!’ employed a QI methodology to recognize barriers to care-seeking and care provision at the facility level and then to identify, test and implement simple and low-cost local solutions that address the barriers. Methods A quasi-experimental design, multivariable interrupted time series analysis, with data coming from 744 health facilities and controlling for potential confounding factors, was used to study the effect of the project. The key independent variables were the change categories (interventions implemented) and implementation phase – Wave 2a (early phase) versus Wave 2b (later phase). The outcomes studied were early antenatal care (ANC), skilled delivery, facility-level under-five mortality and attendance of underweight infants at child welfare clinics. We stratified the analysis by facility type, namely health posts, health centres and hospitals. Results Several of the specific change categories were significantly associated with improved outcomes. For example, three of five change categories (early ANC, four or more ANC visits and skilled delivery/immediate postnatal care (PNC)) for health posts and two of five change categories (health education and triage) for hospitals were associated with increased skilled delivery. These change categories were associated with increases in skilled delivery varying from 28% to 58%. PNC changes for health posts and health centres were associated with greater attendance of underweight infants at child welfare clinics. The triage change category was associated with increased early antenatal care in hospitals. Intensity, the number of change categories tested, was associated with increased skilled delivery in health centres and reduced under-five mortality in hospitals. Conclusions Using an innovative evaluation technique we determined that ‘Project Fives Alive!’ demonstrated impact at scale for the outcomes studied. The QI approach used by this project should be considered by other low- and middle-income countries in their efforts to improve maternal and child health

Survey of Stream in Central Kentucky

Aquatic insect communities are often used as a measure of stream health as some species are sensitive while other species are tolerant to habitat degradation and poor water quality. This study measured and compared aquatic insects, habitat scores, dissolved oxygen, PH, and conductivity from three streams in Central Kentucky. The objectives of this study were to compare the data between the three streams, and to determine if the habitat and water quality parameters are effecting aquatic insect communities. Water quality data was collected at each stream with a Hach water quality probe and aquatic insects were collected using the kick-method with a D-frame net. Our results indicate that there is a significant difference (p0.05) in sensitive aquatic insects and habitat score between the three streams although the substrate in Little Six Mile and Student Branch were dominated by bedrock, no cobble or gravel was present to provide habitat structure. Our results indicate that the channelization and therefore habitat degradation of Little Six Mile and Student Branch have negatively impacted the sensitive insect taxa as their absence is linked with the absence of habitat in the bedrock streams. These ecosystems and their biota would benefit from habitat restoration

The relationship between type of antidepressant and neurovegetative symptoms in adult unipolar nonpsychotic depression: an opinion survey.

The bi-directional nature of the neurovegetative symptoms of depression, as well as the differential response to antidepressant medications, underscore the existence of possible subtypes of this disorder. This study surveyed 56 physicians practicing psychiatry in Hawaii for opinions regarding the most effective antidepressant medication for the following symptoms: hypersomnia vs. insomnia, psychomotor agitation vs. retardation, and gain vs. loss of appetite or weight. Fluoxetine was found to be the drug of choice for weight and appetite gain, hypersomnia, and psychomotor retardation. Mirtazapine was viewed as most effective for weight and appetite loss. Trazodone was found most effective for insomnia and nefazodone for psychomotor agitation. It is concluded that subtyping of depression should be investigated at the symptom level and the generalizability of the effects of each specific compound should be tested
