Do pedometers motivate people to walk more?

Physical activity confers many important health benefits. The 'active living message' recommends that adults should accumulate 30 ruin of moderate-intensity physical activity (e.g. brisk walking) on most--preferably all--days of the week, but the populations of most developed countries are not meeting this target. Walking is one mode of activity that most people can do without skills, equipment, facilities or extra expense and walking has less bias in terms of age, sex and social class than facility-based exercise. Thus we need to investigate interventions that promote walking

Does doing housework keep you healthy? The contribution of domestic physical activity to meeting current recommendations for health

Recent lifestyle approaches to physical activity have included the promotion of domestic physical activities such as do-it-yourself or home maintenance, gardening and housework. Although it is acknowledged that any activity is better than none, there is a danger that those undertaking domestic 'chores' may assume that this activity is moderate intensity and therefore counts towards this 150 minute per week target The purpose of this paper was to report the contribution domestic physical activity makes to total weekly physical activity and the relationship between domestic physical activity and leanness in the Northern Ireland population

Availability of specialized healthcare facilities for deaf and hard of hearing individuals.

Context: To allow a medical consultation to proceed successfully, it is essential that physicians are aware of the linguistic and cultural backgrounds of deaf and hard of hearing individuals (DHH) and related communication aspects. Some specialised healthcare facilities have emerged to respond to the specific needs of people who are DHH. Objective: This study aims to provide insight into the various types of general healthcare facilities available for DHH individuals. By sharing and comparing experiences and results improvements can be made. Design, Data Sources and Study selection: A systematic review of the literature on specialised healthcare for DHH people was performed. The following databases were searched: PubMed, Web of Science, PsycINFO, Academic Search Premier, CINAHL and Embase. After independent extraction per article by two readers, fifteen articles were included in the systematic review. As it appeared that not all existing locations of facilities of which we were aware were described in the literature, we expanded the data collection with internet searches, specific literature searches and unstructured interviews. Results: Some countries have developed facilities to meet the needs DHH people Experts and patients’ groups report that the perceived quality of healthcare and health education in specialised healthcare settings is higher compared to regular healthcare settings. Two projects undertaken to improve the health related knowledge level of DHH people, proved to be effective. Conclusion: Some facilities or combinations of facilities are used in different countries to attempt to meet the needs of DHH patients. These facilities are rarely described in the scientific literature. Further development of specialised healthcare facilities for DHH patients, which should include high quality studies on their effectiveness, is imperative to comply with medical ethical standards and respect the human rights of DHH people

Primordial nucleosynthesis with a varying fine structure constant: An improved estimate

We compute primordial light-element abundances for cases with fine structure constant alpha different from the present value, including many sources of alpha dependence neglected in previous calculations. Specifically, we consider contributions arising from Coulomb barrier penetration, photon coupling to nuclear currents, and the electromagnetic components of nuclear masses. We find the primordial abundances to depend more weakly on alpha than previously estimated, by up to a factor of 2 in the case of ^7Li. We discuss the constraints on variations in alpha from the individual abundance measurements and the uncertainties affecting these constraints. While the present best measurements of primordial D/H, ^4He/H, and ^7Li/H may be reconciled pairwise by adjusting alpha and the universal baryon density, no value of alpha allows all three to be accommodated simultaneously without consideration of systematic error. The combination of measured abundances with observations of acoustic peaks in the cosmic microwave background favors no change in alpha within the uncertainties.Comment: Phys. Rev.
