This study sought to find out whether plastics dependence can promote gender bending behaviors among preschool boys along a shoreline community in Bacolod City, Philippines. Descriptive statistics was used in this study to describe the main features of collection of observation regarding plastic dependence in quantitative terms. T -test of independent sample was used to answer the question: Is there a significant difference in the level of plastic dependence when respondent mothers were grouped as with gender bending boys and with non gender bending boys. Out of 200 mothers living along a shoreline community in Bacolod City, Philippines, 136 were made the actual respondents of the study. The influence of family of chemicals known as phthalates, which are widely used to make plastics more flexible and can be found in food wrappers, cosmetics and electrical equipment were shown to affect the normal gender development in baby boys. Findings showed that mothers who acknowledged presence of gender bending activities among their boys had a higher level of plastic dependence than mothers who did not report any gender bending activity among their boys. Plastics dependence may be a factor in the development of gender bending behavior among preschool boys.
