AbstractBlood pressure (BP) control is a key intervention to decrease cardiovascular diseases (CVD), the main cause of death in low and middle-income countries (MIC). Scarce data on the determinants of BP control in Latin America are available. Our objective is to explore the role of gender, age, education, and income as social determinants of BP control in Argentina, a MIC with a universal health care system. We evaluated 1184 persons in two hospitals. Blood pressure was measured using automatic oscillometric devices. We selected those patients treated for hypertension. The average BP of less than 140/90 mmHg was considered a controlled BP. We found 638 hypertensive individuals, of whom 477 (75%) were receiving antihypertensive drugs, and of those, 248 (52%) had controlled BP. The prevalence of low education was more frequent in uncontrolled patients (25.3% vs. 16.1%; P < .01). We did not find association between household income, gender, and BP control. Older patients had less BP control (44% of those older than 75 years vs. 60.9% of those younger than 40; test for trend P < .05). Multivariate regression indicates low education (OR 1.71 95% CI [1.05, 2.79]; P = .03) and older age (OR 1.01; 95% IC [1.00, 1.03]) as independent predictors of the lack of BP control. We conclude that rates of BP control are low in Argentina. In a MIC with a universal health care system low education and old age but not household income are independent predictors of the lack of BP control.

Purpose
Despite the significance of knowledge sharing for competitive advantage in networked businesses like franchising systems, there is a lack of comprehensive understanding regarding the strategic value of knowledge sharing in the context of franchising. In particular, the specific contribution of information and communication technologies (ICTs) in facilitating interorganizational knowledge exchange among franchising members remains inadequately understood, particularly in emerging economies. Therefore, this study aims to explore the mechanisms involved in the knowledge-sharing process facilitated by a virtual learning environment (VLE) within franchising networks and examine the role of VLEs in facilitating knowledge.


Design/methodology/approach
This study uses a multiple-case study approach involving 24 franchisees and the franchisor within a Brazilian franchising network operating in the furniture market to examine the role played by a VLE.


Findings
The results of the study reveal that the introduction of a VLE has played a significant role in fostering enhancements in the knowledge-sharing process among the franchisor and franchisees in the network. Moreover, the results indicate that VLEs play a significant role in overcoming geographical obstacles, thereby enabling efficient knowledge sharing between franchisees and franchisors operating in extensive territorial contexts. Finally, findings indicate that intracommercial competition acts as a prominent barrier, leading to low levels of cooperation and knowledge-sharing intent among franchisees within the network.


Originality/value
This study contributes to the existing knowledge by enhancing the understanding of how ICTs can facilitate knowledge sharing in organizations operating within franchising systems. Furthermore, this paper advances the comprehension of the role of networking franchising configuration and governance in supporting organizational improvements. Additional actionable insights are provided.
