On September 28, 2026, Workforce Health Index (WFI) by Loop Health reported that India’s metropolitan workforce are getting health alerts much earlier than expected.
Poor sleeping patterns, higher stress levels, anemia, blood-sugar deficiency and vitamin dysfunction are appearing in working-age adults, containing people in their 30s.
The findings are intended to assist employers, healthcare providers, and individuals classify rising health risks and support earlier intervention and preventive care.
The WHI 2026 second annual report is based on over 8.16 lakh lab reports, 11,400 medical reports, 9,097 behavioral survey responses (collected between March 6 and April 29, 2026) and around 74,339 hospital claim records from December 2025.
By comparison, the WFI 2025 report consisted solely of blood reports and 3,437 response behavior survey responses.
The report revealed that 81.4% of individuals had insufficient levels of vitamin D, with 60.1% classified as deficient or severely deficient. Additionally, the WHI 2026 report shows a decrease in vitamin D supplementation to 20.4% from 26.2% down from previous year.
Vitamin D facilitates the absorption of calcium in the body and strengthens bone structure; a lack of this essential vitamin compromises bone health well beyond just a low lab reading.
Regionally, Bengaluru reported the highest vitamin D insufficiency rate at 83.9%.

Vitamin B12 insufficiency was recorded at 69.6% (defined at 300pg/ml), up from 68.2% in 2025.
Vitamin B12 helps maintain the myelin sheath around nerve fibers. Deficiency can result in fatigue, difficulty concentrating, numbness and problems with balance issues — and neurological symptoms can manifest even in the absence of anemia.
Hemoglobin is an iron-bearing protein in red blood cells (RBCs) that transports oxygen throughout the body.
Anemia emerged as another critical finding in the report : approximately 34.6% of 4,375 women tested had hemoglobin levels below 12g/dL, whereas 8.9% of 5,210 men reported Hb below 13g/dL.
City-level findings revealed striking geographic variations — in Mumbai 52.3% of females were below the clinical threshold in comparison to 23.2% in Bengaluru.
Around 4 in 10 blood sugar test results in the sample fell above the normal range, with the majority of affected individuals falling into the prediabetes range.
An HbA1c test reflects average blood sugar over roughly three months. Out of the 7,088 HbA1c results analyzed across the employees and covered family members, 25.4% were in the prediabetes range and 13.3% in the diabetes range.
Notably, elevated HbA1c levels were twice as common among individuals in their 30s (~33.0% ) in comparison to 20s.
Further, men in their 30s accounted for a dispropionate share — experiencing approximately 2.4 times the diabetes range of women in the same group.
Geographically, Mumbai recorded the highest prevalence of elevated blood sugar at women's share, reaching around half (49.8%) across the five metro cities at 46.8%.
A ICMR-INDIAB study revealed 136 million adults with prediabetes and 101 million with diabetes in 2021.

Lower levels of HDL are a recognized risk marker, whereas lower levels of LDL have clinical evidence supporting a reduction in atherosclerotic events, such as heart attacks.
The report analyzed important cardiovascular health indicators among urban professionals.
Among 8,054 individuals, 62.6% presented LDL levels at or above 100mg/dL while 47.3% of 4,824 tested employees recorded HDL levels below 40mg/dL.
At the city level, Hyderabad recorded the highest prevalence of low HDL at 50.6%, followed by Pune at 47.8%, Mumbai at 46.3%, Bengaluru at 41.8% and Delhi NCR at 39.1%.
Together, these findings offer a clear geographic window into lipid health indicators across India’s major urban centers.
Sleep exerts far more influence over an individual’s body than just deciding how rested they feel.
In this year’s report factors like sleep deprivation and elevated stress emerged as defining sensitivity in workforce health.
Approximately 30.75 of respondents reported sleeping fewer than six hours per night, while 40.4% reported experiencing high stress levels in the past week.
Among women, these challenges were significantly more noticeable: 47.4% reported high stress levels, and 36.3% reported sleeping fewer than six hours per night.
Combining these recovery shortages, the proportion of working professionals who do not exercise regularly climbed to 30.9%, in comparison to 28.0% in the WHI 2025.
The findings also captured the change in patterns in how professionals access health information.
19.8% of respondents reported using AI tools such as ChatGPT for health-related queries, while 19.7% relied on Google. Approximately, half 54.0% said they consult doctors or healthcare professionals.
Because respondents were allowed to select multiple sources of information, this report reflects the growing presence of digital tools along with traditional healthcare sources in everyday health information seeking.
