Background: Obesity is now reported as an epidemic in many developed countries, and it is an
emerging public health concern in developing, transitional, and newly developed countries. The
incidence of obesity increases during adolescence and persists into adulthood and becomes irreversible.
In addition to biological causes like inheritance, cultural factors (such as dietary knowledge,
attitudes and behaviours), socio-demographic factors may also play a central role in the etiology
of obesity. The aim of the study was to describe young adults’ knowledge and perceptions
about obesity, with a focus on comprehensibility and meaningfulness of obesity in their daily lives
and its health implications. Methods: A cross-sectional descriptive design was used with 96 participants
aged 18 - 35 years. The respondents’ body mass indices (BMI) were calculated from
self-reported weights and heights. Descriptive analytical, statistical methods were used for data
analysis. Results: The youths had good knowledge about obesity, its causes and associated complications.
Generally, negative attitudes toward obesity were reported. Some perceived obesity as
the ideal body image among today’s youths while others perceived obesity as something that was
beyond their control. Identified knowledge gaps were in the area of obesity and nutrition knowledge,
food preferences and implications to health. Knowledge deficit about obesity might lead to
poor health-related behaviours with its associated complications. Conclusion: There is a need to
intensify community-focused health education as a preventive strategy to empower the youths to
take charge of their health and change their perceptions about obesity.
