A community-based intervention study involving family gardens with aromatic herbs on changes in dietary and urinary sodium.

OBJECTIVE: To measure dietary and urinary changes in sodium (Na) intake and excretion through the implementation of family gardens with aromatic herbs and workshops for cooking, using the herbs as a substitute for salt and seasoning powder. METHODS: Thirty-five participants from a neighborhood of Mexico City were included. A general questionnaire was administered to collect information on sociodemographic factors. At baseline and 3 months later, a dietary evaluation was conducted, and 24-hour urine samples were collected. Food items reported were classified according to the NOVA classification. Visits to participants´ houses were conducted to measure the amount of salt and seasoning powder added to food during the preparation of meals as well as a home food inventory. All participants were given a family garden with 6 aromatic herbs and a recipe book. The intervention included 7 cooking and 3 garden care workshops. Qualitative information on the experience was also collected. Linear regression models were run in order to estimate the contribution of each NOVA group, salt, and seasoning powder to total dietary Na intake. RESULTS: Participants were 44 years old on average and were mainly women (91.4%). The participation compliance in the workshops was 69.5%. After 3 months, there was a Na intake mean reduction of 976 mg. There was also a reduction in the excreted urinary Na of 325 mg per day. CONCLUSION: A positive level of involvement in this program had a direct influence on dietary habits to lower Na consumption.

Associations of the COVID-19 pandemic with social well-being indicators in Mexico.

BACKGROUND: Public health measures for COVID-19 containment have implied economic and social life disruptions, which have been particularly deleterious in low- and middle-income countries (LMIC) due to high rates of informal employment, overcrowding, and barriers to accessing health services, amongst others social determinants. Mexico, a LMIC, is a country with a high COVID-19 mortality in which there has been a very limited governmental response to help mitigate such COVID-related disruptions. This study analyzes the association of the first wave of the COVID-19 crisis in Mexico with four well-being indicators: income, employment, anxiety, and food security. METHODS: It uses pooled cross-sectional data (n = 5453) of five monthly nationally representative surveys collected between April and August 2020. Probit models are estimated to assess the association of the pandemic with job loss and anxiety; a multinomial logistic regression is estimated for food security, and an ordinary least squares regression assesses the association between the pandemic and changes in household's income. RESULTS: Females were significantly associated with worse outcomes for the 4 well-being measures with an average reduction of 2.3% in household income compared to pre-COVID-19 levels, an increased probability (6.4 pp) of being in a household that had lost jobs, decreased probability of food security (6.9 pp), and an increased risk of anxiety symptoms (8.5 pp). In addition, those with lower SES and household with children also reported worse outcomes for employment, income and food security. The month variable was also statistically significant in these models suggesting that as more months of the pandemic elapsed the effects persisted. CONCLUSION: The currents study documents how the COVID-19 pandemic is associated with different well-being indicators in a LMIC. It suggests the urgent need to take actions to support vulnerable groups, particularly women, households with children and those in the lowest SES. If policy actions are not taken, the pandemic will increase social and gender disparities, and will jeopardize childhood development.

How many men who have sex with men and female sex workers live in El Salvador? Using respondent-driven sampling and capture-recapture to estimate population sizes.

OBJECTIVE: To estimate the numbers of female sex workers (FSW) and men who have sex with men (MSM) in San Salvador, El Salvador. DESIGN AND METHODS: A capture-recapture exercise was conducted among MSM and FSW in San Salvador in 2008. The first capture was done by distributing key chains to both MSM and FSW populations through local non-governmental organizations (NGO) that work with these groups. The second capture was done during the course of an integrated behavioural and biological survey (IBBS) using respondent-driven sampling (RDS). The proportion receiving a key chain estimated from the IBBS study was adjusted by RDS-derived weights. RESULTS: The first capture included 400 FSW and 400 MSM. Of the 624 MSM interviewed in the IBBS, 36 (5.8% crude; 3.2% adjusted RDS) had received the key chain. The estimated population size of MSM in San Salvador was 12 480 (95% CI 7235 to 17 725). Of the 663 FSW interviewed in the IBBS, 39 (5.9% crude; 6.9% adjusted RDS) had received the key chain. The estimated number of FSW was 5765 (95% CI 4253 to 7277). CONCLUSIONS: The capture-recapture exercise was successfully linked to an IBBS to obtain city-level population sizes for MSM and FSW, providing valuable information at a low cost. Size estimates are crucial for programme planning for national AIDS programmes, NGOs and stakeholders working with these populations and for HIV projection models.
