Research on resilience and the public health approach to the problem of youth violence have brought a new awareness of, and research on, protective factors -- those aspects of the individual and his or her environment that buffer or moderate the effect of risk.
Natural family planning. Natural family planning (NFP) comprises the family planning methods approved by the Roman Catholic Church and some Protestant denominations for both achieving and postponing or avoiding pregnancy. In accordance with the Church's teachings regarding sexual behavior, NFP excludes the use of other methods of birth control, which it refers to as artificial contraception.
If used according to teaching and instructions, natural family planning methods are up to 99 per cent effective, depending on which method is used. This means that up to one woman in 100 will get pregnant in a year. If natural family planning methods are not used according to instructions, more women will get pregnant.
