Thelma Assis — universally known by her nickname Thelminha — is a Brazilian physician who rose to national prominence after winning Big Brother Brasil 20 (BBB20) in 2020, one of the most-watched seasons in the franchise's history. She parlayed that platform into a substantive TV Globo career, joining the long-running health program Bem Estar as a presenter, a role that neatly bridges her medical credentials with her public visibility. Her YouTube channel, launched in the wake of BBB, embodies a philosophy of turning life's obstacles into building blocks — her own framing in the channel description — though the platform has been dormant for several years, with Instagram now serving as her primary and most active stage.
Her Instagram output spans health education, racial equity advocacy, lifestyle content, and branded partnerships, a mix fully consistent with her dual identity as a practicing physician and TV personality. Appearances on the talk program Sem Censura and a Harper's Bazaar Brasil cover illustrate her comfortable range across health journalism and mainstream culture. Her audience splits evenly by gender, and her engagement rate runs substantially above category norms, indicating genuine audience investment rather than passive reach. With a rate card placing her firmly in premium macro-influencer territory, she is a natural fit for health, wellness, and social-impact brands. Her compounded identity — Black physician, BBB champion, TV presenter, and racial-equity advocate — gives her a durable and structurally differentiated position within Brazil's creator economy.
Thelminha reaches an audience concentrated in Brazil primarily through YouTube, and is best activated via long-form YouTube integrations, Instagram Reels and Stories. Their sponsorship history skews toward Broadcast / Media, E-commerce / Retail, a clear signal of fit for brands in those categories. Demonstrated partners include TV Globo (Bem Estar / Sem Censura) and Amazon Brasil. Engagement on YouTube runs around 14.3%, which points to an audience better suited to category-relevant, mid-funnel campaigns than to pure-reach buys. The channel's mix of long-form YouTube integrations and Instagram Reels and Stories lets a sponsor choose between short awareness placements and longer, more detailed integrations. Because the audience follows fitness content rather than arriving through untargeted reach, sponsorships that match the channel's subject matter tend to convert more efficiently than broad placements. A consistent, on-topic posting focus gives sponsors a predictable, brand-safe environment, lowering placement risk compared with broad, general-interest channels. Campaigns here are best measured on qualified engagement and consideration within the niche rather than on raw impression volume. For Brazil-focused brands in Broadcast / Media and related categories, Thelminha offers a defined, creative-fit audience rather than broad, low-intent impressions.

Yes, Thelma Assis won BBB20, the twentieth season of Big Brother Brasil on TV Globo. Her warm, authentic personality on the show is exactly why fans coined the nickname Thelminha — and she carried that momentum into a media career on the same network after her win.
Her full name is Thelma Assis. She explains on her YouTube channel that the nickname Thelminha comes naturally — according to her, anyone who spends five minutes with her ends up calling her that, which is why she named the channel after it.
Yes, Thelma Assis is a licensed physician. She frequently brings her medical background into her content, covering public health topics like newborn screening tests and disease prevention, and her Instagram bio explicitly identifies her as Médica alongside her presenting role.
She is a presenter on Bem Estar, TV Globo's health and wellness program. The role is a natural fit given her background as a doctor, and much of her Instagram content reinforces health education themes she covers on the show.
She addresses this directly in her YouTube bio: she says anyone who meets her quickly drops the formal 'Thelma' and starts using the affectionate diminutive Thelminha within minutes. It reflects her approachable, warm public persona, and she leaned into it as her full brand identity.
Yes, she appeared on the July cover of Harper's Bazaar Brasil. The feature was framed around strength and plurality, themes that tie into her ongoing public advocacy around Black Brazilian women in media.
On her appearances on Sem Censura, she has spoken openly about structural racism and its real-world impact, combining her platform as a public figure with her medical perspective. Her posts signal that she treats these conversations as part of a consistent commitment, not one-off appearances.
The teste do pezinho is Brazil's newborn heel-prick screening test. Thelminha used her platform to explain the difference between the basic version offered free through the SUS public health system and expanded versions, a practical health-education post typical of how she bridges her medical career and her social media presence.
She consistently uses her platform — including her TV appearances and social media — to highlight structural racism and its effects. Her use of the hashtag #pretanaglobo reflects her identification with the visibility of Black Brazilians on mainstream television, and she has described anti-racism work as a personal responsibility rather than an optional stance.
Her YouTube channel has been dormant for several years, with no recent uploads. Today her active presence is almost entirely on Instagram, where she has built an audience of over four million followers and maintains strong engagement well above the typical category average.
