A large percentage of Bolivians oppose efforts to bring marriage equality to the largely Catholic nation.

According to a survey conducted by local outlet Pagina Siete, 74 percent of Bolivians oppose same-sex marriage and 67 percent oppose legalizing access to abortion.

The news comes ahead of a planned July visit to Latin America by Pope Francis. The pope's visit will take him to Ecuador, Bolivia and Paraguay.

In 2012, three years after Bolivians approved a new constitution which prohibits discrimination based on sexual orientation and gender identity, while defining marriage as a heterosexual union, a bill which sought to allow gay couples to marry was introduced by Senator Hilda Saavedra. It stalled from lack of support.

Last year, Rolando Villena, Bolivia's public advocate, publicly backed civil unions for gay couples.
