At 7 a.m. one recent morning, a nurse and two church workers got out of a van at a morning market here to set up tables, plastic tools and two red canopies.

The trio, all wearing white polo shirts with red trim, set up their booth not to sell produce, meats or trinkets like nearby hawkers, but instead to conduct health screenings sponsored by the Seventh-day Adventist Church.

This fulltime ministry, called Hope On Wheels, operates five days a week to offer basic health assessments and comfort to those who may be experiencing a severe health challenge. With obesity on the rise, some are surprised to learn they may have diabetes.

For not selling, the team does a brisk business. Dozens visited their booth over the next three hours as they offered tests for blood pressure, glucose and body mass index. Later, they'll visit the homes of regular visitors to their booth, checking to see if guests have called their doctor about an issue or adjusted their diet as suggested.
