Teen pregnancy in the Philippines

Teen pregnancy rate is down but the actual number of pregnant teens has gone up.

In 2012, about 43,000 Filipino teens got pregnant at age 17. This was 6.7% of all 17-year-old teen girls. In 2022, the teen pregnancy rate among 17-year-olds has gone down to 5.4% but this proportion is equal to 61,000 pregnant teens.

With funding from the United Nations Population Fund (UNFPA), CHSI conducted several studies to understand why Filipino girls get pregnant on the average at age 17.

Teen Romance: How do teens view sex, romance, and relationships?

In 2013, CHSI interviewed 71 students and out-of-school youth in Albay Province in a series of focused group discussions. We learned that:

  • Romance begins with a “Hello! How are you?” text message.
  • Parents are never their source of information about romantic relationships and sex.
  • An “all-knowing” older friend is usually the go-to person for sex talk.
  • Getting drunk gets somebody pregnant.
  • They do not go to a health center for their teen health concerns.

Teen Moms: Where do teen moms give birth?

In 2016, CHSI reviewed 3,200 birth data records in selected cities and provinces. We found that:

  • The mean age of teen moms was 17.8 years old.
  • 42% gave birth at hospitals but 13% delivered their babies at home.
  • Of 720 births with information about the father of the child, 96% of fathers were older than the teen moms.

Teen Moms and Productivity: How much potential income is lost when teens get pregnant and drop out of school?

In 2016, CHSI and Dr. Alejandro Herrin calculated how much is lost when a teen mom drops out of school and becomes unemployable. We learned that:

  • Getting pregnant reduces a girl’s chance to complete high school.
  • Teen moms are likely to become low-income earners.
  • About 33 billion pesos are lost if teen girls become pregnant and unemployable throughout their lifetime.

Sex Talk with Parents: Are parents ready to talk about sex with their teens?

In 2017, CHSI and the Social Weather Stations (SWS) surveyed 1,000 parents and their teen children. We found that:

  • Filipino parents are uncomfortable to talk about sex and sexuality with their teen children.
  • They cite missing education as a direct consequence of teen pregnancy.
  • 77% of parents agree that a comprehensive sexuality education program be taught in schools.

Access to sanitary toilets in the Philippines

About 705,000 Filipino households still do not have their own toilets.

In 2013, 9% of households in rural villages practiced open defecation. In 2022, this proportion went down to 5%.

 

No Money for Toilets: Why do rural households have no toilets?

In 2014, CHSI interviewed mothers and fathers in Masbate about the practice of open defecation. We found that:

  • Most families lived on lots owned by others. Digging earth for toilet construction is not allowed.
  • They thought that toilets were expensive and beyond their reach.
  • They would build toilets for their children primarily for safety reasons.

Comprehensive sexuality education in the Philippines

Comprehensive sexuality education (CSE) helps young people make safe and healthy choices about identity, relationships, and life goals. Schools can provide accurate and age-appropriate information to prevent early pregnancies, sexually transmitted infections, and gender-based violence.

Readiness of Teachers: Are teachers ready to talk about CSE?

In 2018, CHSI surveyed 700 schoolteachers, principals, and education supervisors about the readiness of the Department of Education (DepEd) in implementing a comprehensive sexuality education. We found that:

  • Teachers and principals are aware of CSE principles and concepts.
  • They are supportive of CSE and the need to integrate this in the basic education curriculum.
  • They need additional skills and tools to be more effective in implementing CSE.

Tuberculosis (TB) treatment in the Philippines

The Philippines has the highest TB incidence rate in Asia.

In 2023, the World Health Organization (WHO) estimated that there were 643 TB cases for every 100,000 people in the Philippines. In 2023, the Department of Health (DOH) reported that over 600,000 people were diagnosed with TB. 

Patient experience in TB clinics: How satisfied are people with TB (PWTB) with services provided in TB clinics?

In 2016, CHSI conducted a mystery client study in 194 public and private TB clinics. We found that:

  • Majority of the TB clinics in the study had good ventilation.
  • Health care workers were generally friendly and welcoming.
  • Having privacy during consultation was the biggest concern.

HIV among MSMs in the Philippines

Majority of persons living with HIV and AIDS in the Philippines are male.

From 1984 to 2023, there were 126,378 reported HIV and AIDS cases in the Philippines. 94% of the cases were male. One in three people with HIV and AIDS is a Filipino male aged 15 to 24 years old.

Condom Use at First Sex: Do young MSM (15-29 years old) use condom at first sexual experience?

In 2016, CHSI surveyed 908 men-having-sex-with-men (MSM) in Quezon, Cebu, and Davao cities. We found that:

  • On average, MSM had their first sexual encounter at the age of 15.6 years old.
  • Only 34% used protection at first sex. Unplanned sex was the most common reason for not using condoms.
  • Only 54% ever had an HIV test.
