Genetics, or inherited traits from parents, also play a role in determining the health status of individuals and populations. This can encompass both the predisposition to certain diseases and health conditions, as well as the habits and behaviors individuals develop through the lifestyle of their families. For example, genetics may play a role in the manner in which people cope with stress, either mental, emotional or physical. For example, obesity is a significant problem in the United States that contributes to bad mental health and causes stress in the lives of great numbers of people. (One difficulty is the issue raised by the debate over the relative strengths of genetics and other factors; interactions between genetics and environment may be of particular importance.)
Since 1974, New Zealand has had a system of universal no-fault health insurance for personal injuries through the Accident Compensation Corporation (ACC). The ACC scheme covers most of the costs of related to treatment of injuries acquired in New Zealand (including overseas visitors) regardless of how the injury occurred, and also covers lost income (at 80 percent of the employee's pre-injury income) and costs related to long-term rehabilitation, such as home and vehicle modifications for those seriously injured. Funding from the scheme comes from a combination of levies on employers' payroll (for work injuries), levies on an employee's taxable income (for non-work injuries to salary earners), levies on vehicle licensing fees and petrol (for motor vehicle accidents), and funds from the general taxation pool (for non-work injuries to children, senior citizens, unemployed people, overseas visitors, etc.)
Medicare Levy Surcharge: People whose taxable income is greater than a specified amount (in the 2011/12 financial year $80,000 for singles and $168,000 for couples) and who do not have an adequate level of private hospital cover must pay a 1% surcharge on top of the standard 1.5% Medicare Levy. The rationale is that if the people in this income group are forced to pay more money one way or another, most would choose to purchase hospital insurance with it, with the possibility of a benefit in the event that they need private hospital treatment – rather than pay it in the form of extra tax as well as having to meet their own private hospital costs.
Lifestyle choices are contributing factors to poor health in many cases. These include smoking cigarettes, and can also include a poor diet, whether it is overeating or an overly constrictive diet. Inactivity can also contribute to health issues and also a lack of sleep, excessive alcohol consumption, and neglect of oral hygiene (Moffett2013).There are also genetic disorders that are inherited by the person and can vary in how much they affect the person and when they surface (Moffett, 2013).
Systematic activities to prevent or cure health problems and promote good health in humans are undertaken by health care providers. Applications with regard to animal health are covered by the veterinary sciences. The term "healthy" is also widely used in the context of many types of non-living organizations and their impacts for the benefit of humans, such as in the sense of healthy communities, healthy cities or healthy environments. In addition to health care interventions and a person's surroundings, a number of other factors are known to influence the health status of individuals, including their background, lifestyle, and economic, social conditions and spirituality; these are referred to as "determinants of health." Studies have shown that high levels of stress can affect human health.
Just as there was a shift from viewing disease as a state to thinking of it as a process, the same shift happened in definitions of health. Again, the WHO played a leading role when it fostered the development of the health promotion movement in the 1980s. This brought in a new conception of health, not as a state, but in dynamic terms of resiliency, in other words, as "a resource for living". 1984 WHO revised the definition of health defined it as "the extent to which an individual or group is able to realize aspirations and satisfy needs and to change or cope with the environment. Health is a resource for everyday life, not the objective of living; it is a positive concept, emphasizing social and personal resources, as well as physical capacities". Thus, health referred to the ability to maintain homeostasis and recover from insults. Mental, intellectual, emotional and social health referred to a person's ability to handle stress, to acquire skills, to maintain relationships, all of which form resources for resiliency and independent living. This opens up many possibilities for health to be taught, strengthened and learned.
