A sample of 1000 tweets was obtained for each stratum and coded as being either about the organization or about personal-health topics. Subcategories for organization included information, engagement, and action. Subcategories for personal health included information and action. Results: Of all LHD tweets (n=3000), 56.1{\%} (1682/3000) related to personal health compared with 39.5{\%} (1186/3000) that were about the organization. Of the personal-health tweets, 58.5{\%} (984/1682) involved factual information and 41.4{\%} (697/1682) encouraged action. Of the organization-related tweets, 51.9{\%} (615/1186) represented one-way communication about the organization and its events and services, 35.0{\%} (416/1186) tried to engage followers in conversation, and 13.3{\%} (158/1186) encouraged action to benefit the organization (eg, attend events). Compared with large LHDs, small LHDs were more likely to post tweets about their organization (Cramer's V=0.06) but were less likely to acknowledge events and accomplishments of other organizations ($\chi$2=12.83, P=.02, Cramer's V=0.18). Small LHDs were also less likely to post personal health-related tweets (Cramer's V=0.08) and were less likely to post tweets containing suggestions to take action to modify their lifestyle. While large LHDs were more likely to post engagement-related tweets about the organization (Cramer's V=0.12), they were less likely to ask followers to take action that would benefit the organization ($\chi$2=7.59, P=.02. Cramer's V=0.08). While certain associations were statistically significant, the Cramer's V statistic revealed weak associations. Conclusions: Twitter is being adopted by LHDs, but its primary use involves one-way communication on personal-health topics as well as organization-related information. There is also evidence that LHDs are starting to use Twitter to engage their audiences in conversations. As public health transitions to more dialogic conversation and engagement, Twitter's potential to help form partnerships with audiences and involve them as program participants may lead to action for improved health.
