Public health in practice: the three domains of public health.

This paper outlines a conceptual model for public health practice by proposing the three domains as a framework to organize and to deliver public health programmes. The model builds on the recognition that public health is everybody's business and therefore, needs a common definitional base. Different levels of skill and a wide range of contributions are needed if public health programmes are to make the most impact. The different domains of practice help to construct a basis for understanding the necessary elements of the public health system and their interactions. Using teenage pregnancy as a case study of a public health programme highlights the characteristics of the model. It demonstrates not only the importance of the role of directors of public health in taking a population-based overview, but also the need for multi-sectoral, multidisciplinary working. The relevance of the public health approach not only to primary care but also to the hospital-based sector becomes apparent, as does its relevance to communities, voluntary sector and local government. Integration of the three domains, a common definition and the framework for the public health system will support effective delivery of health improvement.

Measuring vitality.

Subjective perceptions of mental and physical energy were measured by the use of visual analogue scales (VAS) over the course of a week in a group of normal volunteers. These variables were found to correlate, highly both with one another and with assessments of vigour and fatigue measured with a standard adjectival format. In addition, high correlations were found with a measure of positive affect. These five variables also displayed characteristic patterns of diurnal variation. Physical and mental energy, vigour and positive affect were highest in the morning, falling progressively and significantly over the day. In contrast, fatigue showed the opposite pattern. Extraversion showed positive correlations with physical and mental energy, vigour and positive affect, and negative correlations with fatigue and negative affect, most being significant (P less than 0.05). Conversely, neuroticism showed a negative correlation with the first four energy variables but was positively related to fatigue and negative affect, most correlations again being significant. Physical and mental energy, vigour and positive affect also showed a positive correlation (P less than 0.01) with a measure of happiness. It is concluded that VAS-derived ratings of physical and mental energy are reliable indicators of self-perceived vigour and fatigue. They are easy to record and show sufficient short-term stability to be used in more extensive studies both of well-being and of its physiological correlates.

Short-term variations in stature growth in Ethiopian and English children.

Two groups of young children, one in Addis Ababa and one in Oxford, were measured every calendar month for 6 months. Changes in their stature variability, as evidenced by increasing measurement interval length, are here compared. There is evidence for substantially greater variability in the Addis Ababa children. When the variability is expressed as coefficients of variation both groups show a marked decline with interval length, presumably as constant and additive components of variation become proportionally less important as the mean increases. One constant element is identified in the Addis Ababa children, since a single subtraction from all interval coefficients greater than two months produces the same CV. It is concluded that this probably represents the homeostatic cycle of catch-up growth in this group of children.
