Which of the following is NOT a characteristic of health guidelines?

The correct answer highlights that health guidelines are not exclusively focused on adult populations. Health guidelines typically aim to address the needs of a broad range of demographics, including children, adolescents, and older adults, in addition to adults. This inclusive approach reflects an understanding that health recommendations should be applicable and beneficial across different age groups, considering the unique health challenges and developmental stages of each group.

In contrast, characteristics such as being based on sound science ensure that the guidelines are grounded in rigorous research and evidence, while their development by government bodies and reputable organizations helps to establish credibility and trust. Finally, being recognized as official policy statements indicates that these guidelines are authoritative resources intended to guide public health practice and policy. Therefore, focusing solely on adult populations does not align with the comprehensive aims of health guidelines, making it the correct choice for what is NOT a characteristic of health guidelines.
