ST. PETERSBURG, Fla. &  SEATTLE -- On International Women’s Day, the WTA Foundation and the Bill & Melinda Gates Foundation on Friday unveiled Women Change the Game, a new campaign uniting the power of women’s tennis and philanthropy to elevate women’s health and nutrition as a global priority.

A key component of the campaign is the first-of-its-kind WTA Foundation Global Women’s Health Fund. With an inaugural donation from WTA Tour title sponsor Hologic, in its first year, the Fund will focus on a key aspect of preventive care. It aims to support at least one million women with prenatal vitamins in low and middle-income countries where access to adequate nutrition for maternal health is limited.

“Throughout my life, tennis has given me a pathway to pursue my dreams, and I know first-hand how important it is to have access to the right health care and nutrition,” said Caroline Wozniacki, former WTA World No. 1 and a mother of two. “On International Women’s Day and beyond, I am proud to shine a light on women’s health and nutrition in the hopes that all women can reach their full power and potential.”

Women spend 25% more of their life in poor health than men, according to a 2024 report by the World Economic Forum. This significant health gap impacts women’s quality of life and limits their ability to engage in the workforce and earn a living for themselves and their families. And in the face of global crises -- humanitarian disasters, war, and climate change -- women and girls suffer the worst consequences.

“Every woman and girl deserves an equal opportunity to be her best -- whether in school, at work or on the tennis court,” said Naomi Osaka, four-time Grand Slam singles champion and new mom. “We are stepping up for women in need, because when we champion each other, we all win.”

Today, more than 1 billion women and girls lack access to the good nutrition and healthy diets they need to survive and thrive, with dire consequences for themselves and their children. Across the world, the gender nutrition gap is worsening. Women and girls are 50% more likely to suffer from malnutrition than boys and men. While the majority of expectant mothers in high-income countries take prenatal vitamins throughout their pregnancies, most women in low and middle-income countries lack access to this simple, lifesaving resource. Prenatal vitamins provide key nutrients that dramatically reduce the risk of stillbirth, infant mortality and babies born small and vulnerable, and they improve women’s health.

“It is unacceptable that so many women and girls don’t have access to adequate nutrition and basic care,” said Melinda French Gates, co-chair of the Bill & Melinda Gates Foundation. “The WTA Foundation was founded on the idea of equal opportunity, and that’s exactly what Women Change the Game is about. Nowhere is it more important to level the playing field than women’s health.”

Women Change the Game

Women Change the Game will engage global audiences through tennis -- translating the power of elite athletes on the court into elite influence off the court -- to take on some of the most pressing and urgent issues for women and girls. A critical component of the campaign is the new WTA Foundation Global Women’s Health Fund, which will mobilize resources for lifesaving women’s health and nutrition products and services that are readily available in high-income countries but are difficult to access or altogether unavailable in low and middle income countries.

The campaign features creative assets, including video, digital and social content, that elevate the voices of elite women athletes in service of women’s equality and better health and nutrition for women worldwide. A series of activations across the Hologic WTA Tour will engage corporate sponsors, tournaments, philanthropic partners, athletes and fans to raise awareness and funding for women’s health and nutrition. The campaign drives audiences to to engage on the issues and donate.

The WTA Foundation Global Women’s Health Fund

The fundraising component of the partnership is the Global Women’s Health Fund, with the kickoff donation of $1.5 million coming from Hologic, title sponsor of the WTA Tour and one of the world’s top medical technology innovators focused on improving women’s health and well-being. Collaboration on the Fund marks the latest expansion of the WTA’s and Hologic’s comprehensive, multiyear alliance to elevate women’s well-being. The Fund leverages data insights from sources like the Hologic Global Women’s Health Index, which shows the interlocking importance of preventive care, access to adequate food and shelter, strong educational opportunities, and other critical resources for women and girls of all ages.

“Whether it’s prenatal vitamins for expectant mothers or routine screenings for breast and cervical cancers, we know that early intervention is pivotal to helping women live longer and better,” said Stephen P. MacMillan, chairman, president, and CEO of Hologic. “As the first donor to the Global Women’s Health Fund, we’re teaming up with the WTA Foundation and the Bill & Melinda Gates Foundation in urging others -- businesses, foundations, governments, tennis fans -- to join us in this crucial movement of improving women’s health.”

For at least the first year, every dollar raised through the fund will be directed toward the Child Nutrition Fund, a global initiative aimed at ending child wasting led by UNICEF, with support from the U.K. government, the Children’s Investment Fund Foundation, the Bill & Melinda Gates Foundation, and other partners. UNICEF, a leader in global health and nutrition, has the worldwide footprint and local partnerships necessary to bring products and services directly into the hands of women in need around the world.
